Ubuntu :: Multiple Copies Of 'lt-httpd' Process
May 9, 2011
I recently inherited a server that I'm now looking after, and when browsing the running processes I came across a number of processes labelled:"/usr/local/apache-2.2.6/bin/.libs/lt-httpd -k start"
At any one time there are between 10 and 15 of them running.Googling the issue has been surprisingly unhelpful... can anybody even tell me what this process is, much less what sort of issue might result in multiple running copies? I'm running Debian Etch (release 4.0).

When I select the "Open with...Other Application" context menu item I get a dialog box with multiple copies of the available programs. All of the offending program entries are Wine programs.How do I remove the extra programs from this list.this is a small problem but kind of annoying..

I know that fork() copies the address space of the calling process. Say, however, i have a linked list allocated. Will the list be copied over to the child process's space? If so, i would have to free them in the child process as well as the parent process, correct? Or will the variables be copied but not be pointing to any valid address? Or would it just kind of not do anything?example:
Code:
struct ll_ex {
struct ll_ex * next;
[code]....

I'm using postfix and the always_bcc option to backup the emails which are passed through my MTA. The problem is that (with spamassassin and clamav running as virtual-smtp agents) I get three copies bcc-ed through to the backup account. Is there something I can do to stop the bcc from being carried out on the internal filters and only work on the final send or mailbox delivery?

I have a desktop and a laptop both running opensuse 11.2 with kde4. I have a samba share on my desktop. I tried opening a video on that share from my laptop (wirelessly) with Dolphin/SMPlayer. Here's what happened:
The video started downloading and the system tray notified me it would take 25 minutes. I thought that was too long (video is 350MB) so I checked the download speed and it was about 2 MB/s. It didn't make sense but I let it keep going.
25 minutes and 3.4 GB later, the download finally "finished"--according to the system tray. However, I checked my system monitor and something was still downloading at 2 MB/s. I confirmed with "df -h" that I was losing 2MB of space a second. At this point I only had about 700MB of disk space left so I rebooted (I wasn't sure how else to stop the download).
After digging around on / I found my video at /var/tmp/kdecache-londy/krun and it was 350MB. Then I found multiple copies of the same video, of varying sizes, on /tmp/kde-londy totalling 3GB.
I deleted the tmp files and tried it again. This time instead of clicking on the video to play it, I tried copying it to my laptop. Same thing started to happen but I didn't let it continue.

I have a 64bit linux server with 5 virtual hosts on it. When someone fills out a contact form on one of the sites...I get 15-20 copies of the same email. At first I thought it was the kids clicking send multiple times because the first emails were coming from the children's ministry "Email The Cast" section. But then I started getting multiples from the adult sites too. All contact forms are set to come to me.
What's stranger is that my registration section for one of the sites uses the SAME php script (different file) to email me a notification that someone has registered but I only get 1 copy of that.

I want to take a graphics file and make 10 copies of it to the same directory, each with 001, 002, or some such designation at the end of each file name so they have discrete files names. Is this possible using cp?

I am using qmail in my office. I am noticing this for more than a month. It is my daily routine to check the cpu utilization using top command and by using top different processes can be viewed. the apache process after 1 or 2 days shows cpu utilization of 100%. There is no affect on the server whatsoever of 100% because mail server has 2 processors of 4 core, i think so that may be the reason. Can any one explain why is this happening. What i do after that is i restart the httpd process and cpu utilization comes to normal. What are the reasons behind this and how to solve this permanently.

i'm trying to spawn a daemon-like java process from php on a unix environment, keep the pid for reference and keep it completely independent from httpd processes. I'm using the following code
$command = 'java -cp /myApp/ MyApp';
exec('nohup '.$command.' >> /myApp/myLog.txt 2>&1 & disown & echo $!', $pid);
$pid = (int)$pid[0];
But it gets killed when you httpd restart. I just want it never to get killed except if i call "kill $pid" command.

We had servers that worked fine for years. After updated them to the latest version of CentOS (5.2 with latest updates), they keeps on hanging when being scanned by PCI Verdors (a Credit Card security standard). Basically, the scan causes httpd process to eat up all memory, and the server becomes unresponsive. Normal operations resume after the scan stops for 5, 10 minutes. Output from top looks like the following:
Mem: 1018988k total, 1007168k used, 11820k free, 432k buffers
Swap: 2096440k total, 2096440k used, 0k free, 4528k cached

I've been scanning the apache2 docs for the past few days and have not come up with an answer my following issue:
In my httpd.conf file, at the very end, I have the line
Include conf/vhosts/vhost_*.conf
However, when I run apache checkconfig or try to start apache, it gives me the error:
httpd: Syntax error on line 993 of /etc/httpd/conf/httpd.conf: Could not open configuration file /etc/httpd/conf/vhosts/vhost_1.conf: Permission denied
It appears as if the Include line is correct - in terms of it grabbing the first virtual host conf file. However, I'm confused on the permissions. the /etc/httpd folder is owned by root:root, as are the subfolders. As a test, I chown'd the conf/vhost folder combination and all the vhost files to apache:apache to see if that made a difference, and it appeared to make no difference at all. The log files don't contain anything (assumed because apache isn't starting). If I place the contents of the vhosts in a singular vhosts.conf it works - with the permissions set to root:root. I'd like to avoid having to use one vhosts conf for the configuration I'm trying to achieve - as it would make my life a lot easier.

I tried the google and browsing the known bugs in the sticky before posting this thread.On boot the machine is pegged at 100%. It is a dual-core with 4GB of ram and is running 10.04, 64bit. Also, as time goes on it eats up all the ram till theres maybe 32mb free. What happens is there are multiple 4-10+ identical processes running. seem to be gnome related.The machine sits idle on my floor and runs samba and apache/mysql/gallery for my test website that no on but myself visits.

We are using this url on our testing box and this ip is reverse proxy IP ( 10.192.64.52)
Without reverse proxy:- URL is working fine.
http://10.192.16.77/akc-qa/arsys/ser...TS000000001430
But with reverse proxy its putting escape [%25] in between %3a
[url]
Is it possible to write a rewrite rule to bypass escape [NE] for this particular URL?

I scanned hundreds of pages in gray scale and would like to batch process them to B&W. You can do this using the gimp GUI. what it does is get rid of all the gray shading from reflections off the paper when scanned. So you get crisp white backgrounds with black text and diagrams. I would like to simply do this to the entire group directory at one time as it would be quite a lot of effort to open them and do them one by one.

I have created a simple download schedular with source-code give below :
---------------------record_strokes.sh-------------------
touch /home/student/packs/lynx/logfile
lynx -cmd_log /home/student/packs/lynx/logfile
[code]....
So, this is a simple download scheduler program code. Which creates multiple threads of the downloading process - wget (i could also have used 'curl' instead 'wget').Can you debug this code?

I have some random files in a folder. I want to rename all of the files in a batch process. I have a text file that contains the Currentname of all the files in the folder, as well as a text file with all of the Newname of files in the folder. I want to replace Currentnames with Newnames.
For example, here are the names of the files in the folder:
1.mp4
2.mp4
3.mp4
I have a text file with the Currentname of all the files in the folder:
1.mp4
2.mp4
3.mp4
I have a text file with the proper Newname of the file:
a.mp4
b.mp4
c.mp4
I want to rename Currentname with Newname in the folder. So when I go to the folder the Newname of the files are:
a.mp4
b.mp4
c.mp4

I'm porting C++ application from ARM to MIPS platform. It works now, but I see some strange timing problems. I've seen now that My app process is called multiply time. Here is "top" output:
Mem: 24592K used, 102084K free, 0K shrd, 0K buff, 16864K cached
CPU: 0% usr 99% sys 0% nice 0% idle 0% io 0% irq 0% softirq
Load average: 4.02 2.17 0.95
PID PPID USER STAT VSZ %MEM %CPU COMMAND
1888 1875 admin R 12096 10% 98% ./my_app.exe
code....
I don't see something like this when I compile it for x86, nor ARM.On MIPS I use uClibc instead of glibc.

First post from a very new Linux user....I am trying to create a BASH script that will allow user to provide multiple directory names, Checks if the directory exists and if not create the directory.
I am using the following code:
Which works fine as long as the user enters a single directory name. How can I modify this so it will process all directory names user enters on the read response?

Let's say you want to copy some files from one drive (ext3 over USB) to another (ext4 in local box). You have a few terabytes over a couple million files.You could just use Nautilus, which is what I did. It seemed to have completed normally (after a few days).I wanted to verify that everything copied accurately, but I'm not sure the best way to do this. If I used md5sum, the verification would take all week, so that won't do. I used "du -bs *" and compared the sizes of the folders at the root of the drives. Most of the folder sizes were off somewhat - less than 1MB in any case. For each folder whose size was different, the difference was a multiple of 4096 bytes. This makes me suspect that the information du is giving me isn't precisely the information I assume it's giving me.
Baobab gave me different sizes from what du gave me, and it also gave significantly different sizes between my source and destination drives.I wanted to do a "diff -r source destination", but I don't even have a guess as to how long that would take so I gave up after a couple hours. It wouldn't tell me everything I want to know, anyway (if files are missing vs if files did not copy correctly).
So the help I need is:
1.) Is there a quick way to reassure me that everything copied correctly?
2.) Is there a better way to do such marathon copies? (faster and more reliable?)

Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.
