I am using sabayon 5 - 32bit OS. I experience dullness and sluggish performance now and then.So number of free file descriptors is constantly zero , checked by utilising a while loop sleeping for 5 secs.would this be the root cause of the sluggishness I face in accessing application (media player)Also USB transfer is very very slow and sometimes it gets stuck

a) a process open the same file twice and read through two file descriptors
b) a process does fork and both parent- and child-processes read parallell
c) two processes opens and read from same file.
Its my Friend Problem .any one can tells that how can the file descriptors limits can be raise for the squid. In cache.log running out of file descriptors warning is coming.

View 1 Replies View RelatedI have a weird problem with one of my servers. When system is booted and right before I should se "INIT 2.86 starting..." message, all the messages disappear. Only kernel messages get logged to console and later login prompt, but nothing in betweek (there are 20+ services starting successfully, just without emitting a single character).I checked /proc/PID/fd of the boot script (in my case called /etc/rc.d/rc.boot but that does not matter).
The only significant difference in hardware to other servers is that this one runs RV350 AP [Radeon 9600] graphic card.Now, my question is: where could those FDs go or why are they not opened?Does anyone have a clue about this, or a hint?
Is there any limitation on the number of file descriptors that can be opened. If yes how to find the maximum number of file descriptors that can be opened at a time.
View 2 Replies View RelatedI am quite confused about the following description on fork. Could you please explain it ?The child process shall have its own copy of the parent's file descriptors. Each of the child's file descriptors shall refer to the same open file description with the corresponding file descriptor of the parent.For example, I am opening a socket and then fork. Now, does the child have a separate socket or is shares it with the parent. Does I have any impact on using it in child?
View 2 Replies View RelatedIs there already a program that reads multiple pipes or file descriptors and writes to the standard output (not splitting lines).Like cat, but reading all files simultaneously and preserving lines.It is needed to avoid coding of select/epoll loops or using multithreading in simple programs. Like "select loop for bash".
View 1 Replies View RelatedThis for Kernel 2.6.29.6. I'm trying to code a kernel module that displays process information.
how to count opened file descriptors per task. I have been able to write a module that lists all the current process names along with their pid number in /var/log/messages. Basically, I cycle through the ring of processes using the macro for_each_process(task) and printk the comm and pid of each task. I'm trying to see how many file descriptors each task has open. I've been reading up in books and all over the internet. At first I thought I needed to access max_fds under files_struct, but that just lists the maximum number of file descriptors that can be opened per task, which by default is set at 256. I then thought about counting the elements in the fd_array. But then I learned that every task's fd_array is initially set at 32. Now I know that I need to access open_fds of type fd_set * in files_struct. open_fds is a pointer to all the open file descriptors. The problem is that I don't know how to access a pointer of type fd_set.
Is there a good guide or book that really focuses on type fd_set and open_fds? Every book and resource I've read never really go into depth on this. relationship between files struct, open_fds, and the open file descriptors in task?
I've noticed that when I run:

I have 44% used. It should be much smaller, under 10%. How do I empty the /tmp file or other file to free up space?
I have 2 computers on the same network that i need to link together to transfer files 1 is a web server the other is a minecraft server. the problem is that the file transfer will be constant as the minecraft server will constantly updates files on the web server and I dont want it to go to the router then to come back to the web server. I want to add a second network card to each computer and link them together and use this second connection to transfer the files is it possible?

i have an external harddrive, hooked up by usb. /dev/sdb it came as a fat drive (sdb1). when i realized, i had copied 250 gb to it already. so, i made a new ext3 (sdb2) partition, copied the data from the fat to ext3, and then deleted the fat drive and moved the ext3 it with gparted. it mounted fine after it was moved, but after i tried to resize it, which didn't work, it will not mount.

View 6 Replies View RelatedI've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.
View 2 Replies View RelatedIn trying to solve a friend's lack of foresight, i have currently disabled my system.
I was using dd_rescue to make a copy of a drive with a corrupt and unfixable Partition Table. I was a fool, and had a drive mounted to /media/Storage, but ran the backup to /media/storage.
Thus, dd_rescue completely filled my primary drive before informing me that there was a problem.
I don't really trust myself with command line work, so I foolishly sudo'ed nautilus and deleted the folder /media/storage.
Unfortunately, I didn't realize it, but the available space on the drive still read 0bytes.
I tried Terminal work to do a sudo apt-get clean command, but for some inane reason, the laptop screen won't support the display setting for the Terminal login, so I just had to hope that I was doing it right.
I wasn't, and decided to try working from a Live CD so I could see what I was doing.
the folder /root/.Trash/ doesn't exist on Ubuntu's install drive, and I can't figure out why the properties of the drive say "contents: 241310 files, 3.7 GB" but also "Total capacity: 52.8 GB. Free space: 0 bytes"
Any suggestions on how I can get this to shake out?
I have been working on a free file hosting service. So far its only been for family and friends. Right now I have is open to them off a no-ip free.

Am I asking too much for a FREE OS? Everybody spend their precious time to help others, that's very helpful.But it seems like there is no support from UBUNTU team,how could we even get through the barrier of not using Microsoft's OSes? No free lunch of course, but it seems to me some issues have never really been solved.I read lot's of people have problem with their WIFI, not just for my OLD USB wifi adapter. I don't have problem with WIFI in XP/Server.
I posted here and there, and seems like no answer, and I do not get any reply from UBUNTU support team,forgive me if I run out of google's keywords.I just need a simple answer, is my WIFI going to work in UBUNTU with a layman effort? I like linux and UBUNTU had put great effort in providing me such a great OS, but if a basic internet connection will need to spent sooo much time to setup, and it still doesn't work. IS IT WORTH to switch to UBUNTU at all

Can i do it by using df?if not , can you specify me which one to use?
