Subject: Null pointer deference
Date: Mon, 9 Feb 2004 17:25:00 -0800 [thread overview]
Message-ID: <20040210012500.GP3272@pathfinder> (raw)
Hi All,
I seem to be able to reproduce a null pointer dereference and paging
request errors in 1.2. Can anyone give me any pointers on tracking down
what is causing it?
This is with a 32Mb virtual domain, running debian woody, NFS root,
256Mb swap in a local VD, while running a process which builds openldap,
python2.2.3, and related packages. I'm not sure which package, if any
in particular, is causing this; could be just anything that causes a
similar workload. This particular set of messages appeared before the
virtual domain locked up during the openldap build...
