Rhythmbox stalls my computer. I start it and within 10-20 seconds it starts to search something (i.e. in the right bottom there appears a box with a red box sliding left and right). It consumes all my memory (1 giga) and the only thing it does is identify text files in a general directory, NOT in Music. I have completely removed the install, installed it again, the same text files earlier IDed are still there? Is there an alternative?
Computer details: Intel dual core, Nvidia, 64 bit Lucid. The flaw is that it runs on single memory.
let me know how to clear cache memory ( RHEL 5.1 ) as it consumes almost 100% physical memory.
View 3 Replies View RelatedI am having a php script which is used for bulk mailing. I run the script every minute through cron job. I have mentioned the path of the php script in a .sh file and execute the .sh file through cron job. Every time i run the script it utilizes high memory which results to server crash. how to restrict memory usage for that process to be a minimum one or how to set priority to be low for that process so that it is executed when there is no high priority jobs, so that the server runs normally without going down when the script runs

For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details.

My computer has 4GB installed but for some reason I could only see the 2 of the 4. At first I thought that this was because the XEN virtual operating system manager was running but even after I turned it off the problem exists. I could only see and use the 2GB of memory.

I am using ubuntu 10.10 with gnome desktop on a desktop computer (pentium 4 cpu with 1 Gb memory), and when I use OpenOffice Impress, convert opens up and uses most of my cpu power. Even worse, after closing OpenOffice and all instances of nautilus, convert stays in memory and keeps using most of my cpu power (between 30 and 75 %, acccording to system monitor.Is it normal ? How could I set up my computer to limit convert cpu usage, and to unload from memory after being used.

View 3 Replies View RelatedWhat originally seemed like an easy thing to calculate has given me a big headache. Perhaps someone can help me with my issue. I am trying to find, in particular, how much memory certain application processes are taking. The process always is the same name, main_server, but with an argument to tell it what to do when running as a daemon.
When running the following command against all "main_server" processes, it produces a result in megabytes based on the output of the rss field in 'ps'.
Code:
CALC=0
for ea in
`ps -e -orss=,args= |
sort -b -k1,1n |
pr -TW$COLUMNS |
grep main_server |
grep -v "grep main_server" |
[Code]...
Currently I am left scratching my head. For capacity planning purposes, it would be nice to know how many more 'main_server' processes could run on the system without causing it to swap. Knowing the buffer and cache usage will go down as running processes demand more memory, I prefer to look at the free memory excluding cache and buffers. However, since 'ps' is reporting the processes are using more memory than free reports is in use without those things, I have no way to know how many more processes the system can support. I played around with different fields in 'ps', such as vsize, size, etc, but with no luck in matching up any numbers.
Is there any link where i can get information about below?

View 1 Replies View RelatedI want to test that a process properly kills itself and restarts when it can't allocate needed memory. One idea I had was to start other memory-consuming processes and hope that OOM killer kills the process being tested, but 1) this isn't quite the same; 2) it may kill other processes instead; 3) since this is an embedded system, I don't have any programs available except for the system under test and BusyBox.Is there a more direct way to ensure that Linux won't allocate memory to a process?
View 1 Replies View RelatedI run a memory-hungry process (mkcromfs) which consumes more memory than I have physical memory on my latop, so it is paging and swappin and thrashing all the time and loadavg is about 2 (compcache is already in use with usual swap partition as well), but slowly moving forward (Although I afraid it will finally try to allocate >2GB and crash draining 2 days of thrashing).
When I want to use the laptop for something else, I stop the process, start X server, firefox and other programs. The problem is that when I start Firefox the loadavg jumps to 10 and the system becomes almost unresponsive at all (long time to turn on/off caps lock, slow mouse cursor position updates, slow switching from X server to Linux console, slow login).
The stopped mkcromfs still holds a lot of memory (464.8 MiB and slowly falling) and moves it to swap only when more memory is needed for some other program, which results in a great slowdown.
How to tell the Linux to swap out this process entirely (e.g. I'm not intending to resume it in short term), possibly waking from swap other data? Also it will be useful to be able to specify the exact swap device to swap the given process out (for example, mkcromfs's memory is useless in ramzswap).
Update: Now I just write a 400-600M of data from /dev/erandom to tmpfs and it makes mkcromfs to shrink. Is there more proper way?
I woukld like to know the kernel command or linux kernel file name where i can get the process actual physical RAM usage in linux version 2.6.21 or hiher version.
View 2 Replies View RelatedI am facing an issue where the process starts hanging. When I closely look at the logs I come to know that some of the child processes that are forked by the parent process are not finished.
1) Is it possible that the child processes that are not finished occupy the socket memory of the parent process and ultimately a point is reached where no socket memory is available to fork new child processes.
2) What is the standard limit of socket memory in linux?
3) What is the fate of such child processes (as I have mentioned above)?
4) How to debug such cases so that the exact problematic area is identified?

I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb

Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached
Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.
The more context the better. So far it does not look like it has anything to do with memory.
