Subject: help interpreting oom-killer output
Date: Tue, 20 Sep 2005 15:37:53 -0600 [thread overview]
Message-ID: <43308131.5040104@nortel.com> (raw)
I'm running a modified 2.6.10 on an x86 uniprocessor system. I keep
having processes killed by the oom killer at the same place while
running LTP. The system has gigs of memory, so I find this kind of odd.
Could someone help me interpret the oom-killer output? The first log
looks like this.
oom-killer: gfp_mask=0xd0
DMA per-cpu:
cpu 0 hot: low 2, high 6, batch 1
cpu 0 cold: low 0, high 2, batch 1
Normal per-cpu:
cpu 0 hot: low 32, high 96, batch 16
cpu 0 cold: low 0, high 32, batch 16
