Subject: dentry_cache using up all my zone normal memory
Date: Wed, 21 Sep 2005 10:26:29 -0600 [thread overview]
Message-ID: <433189B5.3030308@nortel.com> (raw)
I'm running 2.6.10 on a pentium-M system with 3 gig of RAM. I'm running
with NFS root, no swap.
Normally at idle I use about 20MB of memory.
When I run LTP everything is fine until it hits the rename14 test.
Invariably during that test the OOM killer kicks in.
With a bit of digging the culprit appears to be the dentry_cache. The
last log I have shows it using 817MB of memory. Right after that the
oom killer kicked me off the system. When I logged back in, the cache
usage was back down to normal and everything was fine.
Anyone have any suggestions?
Chris
