[headache] 3.7.0-rc2 can't handle mutt (with 3.7G mail file) +FF (4tabs) on a 4G memory+4 core system ?
From: Luming Yu
Date: Wed Nov 07 2012 - 09:15:04 EST
Hi,
when I hit Q trying to quit from mutt, the system seemed to begin bump
. I echo l > /proc/sysrq-trigger 3 times. The call traces looks like a
live lock..but I'm not sure,
It is strange that trying to quit from mutt with a big mail file could
trigger a similar "system hang" on a leading edge 4Gmemory+4 core
system as I experienced on a ancient P4 system with 512memory + 1
core... Any ideas? /l
