Subject: 2.6.5-aa3: kernel BUG at mm/objrmap.c:137!
Date: Wed, 14 Apr 2004 12:57:16 +0400 [thread overview]
Message-ID: <200404141257.16731.gluk@php4.ru> (raw)
G'Day,
I've got a bug on 2.6.5-aa3 today
System: Dual P4 Xeon 2.4GHz, 4G ECC RAM - (production web-server) pretty
heavy loaded at most time, but i've got it approximately
at 02:00 (MSD) when no serious load should be.
System remained accessible all the time but operations
with proclist from userspace (i.e. ps, w) appears to be locked.
Here is a trace:
kernel BUG at mm/objrmap.c:137!
