hi list,
during the last weeks i've encounterd some OOM situation here on my little server machine. that happened with some 2.6.9 and 2.6.10 kernels but i never found out what the reason was. the machine was running for 2 or 3 weeks and constantly taking up more and more swap until the OOM killer did his job and killed some task. i decided to reboot then, once i *had* to reboot because the machine has locked up. so i suspect a "memory leak" somewhere. knowing nothing about VM and knowing the term "memory leak" only from hearsay, i just want to know
1) does a memory leak always occur in kernel space? or could some userspace application take up more and more swapspace too? 2) where can i look for the process to blame?
i've already thought about it and i really think a userspace app can also be the bad one here, but "top" and "ps" won't tell me who's to blame. perhaps somewhere under /proc, but i don't know where. can someone tell me where to look for?
currently i'm running 2.6.10-rc1-bk19 and 436MB swapspace is already used. that's not "normal" for this machine and i can from daily "free -m" outputs that more and more swapspace is used - but i don't know by what!
thanks, Christian. - -- BOFH excuse #227:
