Kernel Memory Issues (2.6 and later)
Hello!
Once again I have to report: Linux 2.6 seems to have problems managing memory.
After working on a laptop system (with Mozilla, X 4.3.99, Opera, 4xterms) for some hours the system becomes very slow.
It looks like the system has no memery left, partly programs get killed (Out of Memory) although there is plenty memory left.
I tried to kill processes to see whether one processes has a memory leak, but that's not the case.
I even tried to kill all processes and restart everything (with sysrg+k) but this didn't show any success.
Any ideas where the problem is?
Nico

No. It would help if you showed us some output from 'vmstat 5' near when the system runs out of memory, and maybe an overview of how much memory you have and how much is taken by programs.

flapp:~ # vmstat 5
-bash: vmstat: command not found
what package is that, where can I get it?
I would like to help to debug it, but I need some help from other kernel developers, as I don't write much kernel code.
Have a nice day,
Nico

Procps. As to where you get it, ask your distribution vendor.
