Subject: ~500 megs cached yet 2.6.5 goes into swap hell
Date: Wed, 28 Apr 2004 14:27:47 -0700 [thread overview]
Message-ID: <409021D3.4060305@fastclick.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 362 bytes --]
Same thing happens on 2.4.18.
I attached sar, slabinfo and /proc/meminfo data on the 2.6.5 machine. I
reproduce this behavior by simply untarring a 260meg file on a
production server, the machine becomes sluggish as it swaps to disk. Is
there a way to limit the cache so this machine, which has 1 gigabyte of
memory, doesn't dip into swap?
Thanks,
Brett
