Subject: Re: dentry_cache using up all my zone normal memory -- also seen on 2.6.14-rc2
Date: Wed, 21 Sep 2005 13:46:35 -0600 [thread overview]
Message-ID: <4331B89B.3080107@nortel.com> (raw)
In-Reply-To: <43318FFA.4010706@nortel.com>
Just for kicks I tried with 2.6.14-rc2, and got the same behaviour.
/proc/slabinfo gives the following two high-runners within a second of
the oom-killer running:
dentry_cache 3894397 3894961 136 29 1 : tunables 120 60
0 : slabdata 134307 134309 0
filp 1216820 1216980 192 20 1 : tunables 120 60
0 : slabdata 60844 60849 0
The oom killer gave the following output:
oom-killer: gfp_mask=0xd0, order=0
