2.6.8.1 memory issues
From: Max Michaels
Date: Mon Sep 20 2004 - 09:36:16 EST
I posted this issue yesterday but now I've seen it happen on 4 servers
in exactly the same manor. Just curious if anyone else has seen it.
I am having issues with 2.6.8-r1 with memory being eaten by the kernel.
Top reveals that only about 35% of the memory (3GB) is being used but
the actual count of free memory is only about 10MB. /proc/slabinfo shows
no odd numbers and /proc/meminfo shows the same 10MB as the top total.
No processes account for this memory, so I'm assuming it must be the
kernel. Eventually, I run out of memory and OOM-killer starts killing
processes until it frees up some memory (about 250MB each time) and then
gets in an endless cycle of doing this until rebooted. Is there some
troubleshooting method I am missing or is this a known issue?
Please personally CC me on any response.
