I'm running 13.1 on a Dell Latitude D630 with 4GB of RAM. My problem is that Slackware doesn't seem to see all of the available memory. Here are the #s being reported (just including pertinent #s rather than all output)...

I have got four webservers and one fileserver, all running Karmic and kernel 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux.A folder on the fileserver has been exported using NFSv3 with these options: rw,async,no_subtree_check
and mounted on all four webservers with these options: efaults,rsize=32768,wsize=32768,noatimeThe webservers run Apache+PHP+APC. Some php-files include other php-files from the nfs mount, and are requested by users very frequently (~ 100 times per second). Sometimes but not always if I alter an included php-file using FTP (the FTP server is ProFTPD and runs on the fileserver), the file seems missing:user@webserver1: ~ $ ls --full-time -al /path/to/included/file.phpls: cannot access /path/to/included/file.php: No such file or directoryI can repeat this command for hours, but the file keeps missing. Until I query the directory:user@webserver1: ~ $ ls --full-time -al /path/to/included/ | grep file-rwxr-xr-x 1 1002 1002 14294 2010-07-04 21:11:30.000000000 +0200 file.php
I recently upgraded to a bigger hard disk. I used CloneZilla to copy my 150GB ext3 /home partition on my Ubuntu system to a shiny new 800GB ext3 /home partition. However, I've filled it up to almost 150GB, and I keep getting warnings that I have only 300MB available. It looks like the free space is being reported incorrectly. GParted recognizes the size of the partition as 800GB, and Nautilus reports the same when I boot from a live CD. I've tried using tune2fs to remove the reserved blocks and e2fsck -f to fix any errors, but nothing's changed.

I know the system has 4096 MB of RAM installed, but why does it show only 3466 MB? Can this be interpreted as total "available" memory? Perhaps the missing 630 MB is being used by the kernel and cannot paged out?
I also tried this on on an Embedded Linux system and saw a similar result. The DRAM chip has 128 MB, but only 124 MB shows up in vmstat.
i got a RHEL 5.2 machine.and i noticed that the total used memory(as shown in "free" command) is 3GB higher thanthe sum of RSS size of all processes(collected using "ps aux").i know that its not suppose to be exact because RSS counts ultiple times shared memory (so actually it suppose to be higher than the used memory).the server runs apache which runs a pretty heavy php program.my suspicion is that its memory leak?

I wrote a program that multiplies 2 matrices using multi-threads and another one using multiple processes and shared memory. Both in C.I need to find the total memory usage of these programs. I know of the top command, but when my matrices are relatively small they don't even show up on top because they complete so fast, how can I find the memory usage for these instances?Also, how can I find the total turnaround time of my programs?

View 7 Replies View RelatedI want to calculate the total amount of memory used by the system, Someone please confirm if the below formula is correct.Quote:
((memUsed-mebBuffers-memCached)*100)/memUsed => totalMemoryUsed%
Code:
free -o
total used free shared buffers cached
Mem: 8167004 8115292 51712 0 87680 1444676
Swap: 8388584 3252996 5135588
((8115292-87680-1444676)*100/8115292) => 81%
As per the above calculation 81% of memory is used.Is this correct? and if so Am I running out of memory?what is the limit in % that I should maintain for a better performance?
I am trying to write a script to calculate the total amount of installed memory to use during an anaconda kickscript, so the swap file is created at 2 x the installed memory. I so far have the amount of installed RAM DIMMS but need a way to total them up and produce a varible I can use in the pre section of the install.
Code:
dmidecode -t 17 | grep Size | awk ' { print $2 }'
Output:
2048
2048
Note: on some servers there could be from 1 DIMM up to 16 DIMMS installed so the script needs to be able to handle this. I also can not use bc as it does not exist during the install stage. I am guessing I need a while loop to do this and use expr but do not know where to start for this logic.

I don't understand why, but my Slackware is totally crash after ~10min work. My guess is Nvidia is fault. Which logs I could see where the problem is? X (startx) work fine. My video card is: geforce 240. installed slackware 13.37 64 bit.
View 6 Replies View RelatedI have installed Slackware 13.1 without a problem and have a working wired ethernet connection. However I need to set up wireless but each time I try to do this using wicd I have a total system crash during the start up screens at the very last line before the welcome line appears.
Nothing works to resolve it, and I need to press and hold the start button and restart. I have checked the md5sum, installed the software again several times but the same happens each time which results in me having to reinstall.
I have installed wicd using slackpkg update, then slackpkg install wicd.
I have also tried downloading wicd from the slackware /extras folder and installing it on its own. Either way the same happens.
I have tried various manual approaches to setting up wireless following various links but again without success.
I now have a clean install again but am not wanting the same to happen.
Can anyone suggest what I might need to do?

I'm running Ardour, and when I launch it I get the following:

Just wondering now I see computers everywhere with 6G of ram or more if the new 32b kernels are going to be setup for large amounts of ram or will they still need to be recompiled? Also will there be better ssd support for things like "trim"? I know you edit the fstab to get the Linux version of trim but I am just wondering if stuff like that will just be automatic or if I will continue to need to tweak. I like to tweak but sometimes its the lack of need for tweaking that makes me like slack.

2 sets of skype logs on work PC (Windows) - and I forgot to take a copy when I finished the assignment - and on my own Slackware PC. Would be very useful to be able to have only one set (and same for instant message logs) on my usb memory stick. Is this possible?
View 1 Replies View RelatedI used mkinitrd to build an initrd from the slackware 2.6.37.6 sources. Lilo throws the following: "Warning: The initial RAM disk is too big to fit between the kernel a the 15M-16M memory hole. It will be loaded in the highest memory as though the configuration file specified "large-memory" and it will be assumed that the BIOS supports memory moves above 16M."
Also, I am running swap, / and home on an encrypted volume group. When the initrd boots (but prior to mounting the encrypted vg) I get a message saying that no modules are found-sounds like a daft question but is this expected? I expect that this is because initrd is looking for modules, but can't find them because the relevant partition isn't mounted.
230Gb HD, I recently partitioned a 90Gb slice, and ran 10.10 on it for a while, but due to not using it, I fired up gparted off a live disc last night and got rid of the partition. I got Gparted to make a 5gb swap, and the rest for 10.04, all is fine, rebooted to 10.04, updated grub, it removed the entry for 10.10, but reports that my hd is only 140gb, and sda2 is a 5gb swap. What gives? Where's my disc space?

Whenever I insert a dvd or a cd, it automatically mounts to /media/[name], Like for example, the DVD I have in now mounts to /media/TBC3.2.0 (TBC3.2.0 is the name of the disc itself).

I have noticed this now for the 125 time that when you mount a volume and use mount to see if it is ro or rw, it says rw, but actually is read only.
Why is mount reporting it wrong?

I've been seeing things like this in Firefox since installing:

Espaol
where the is a special/accented character. I've also been seeing the in places that seem likely to have some kind of quote mark, probably curved quotes. I can see straight single and double quotes. To correct this, I've tried changing the display font and the character encoding. I've also looked at the Mozilla Add-On site to see if I could find a plug-in to fix it, to no avail.
What should I try now? Currently I'm using Liberation Sans with UTF-8. I'm a native English speaker so I need a western encoding (I think), but I'd still like other characters to display properly.
