Comment 2 Radek Steiger 2012-12-10 18:16:04 UTC

I used a cluster.conf similar to that provided by Chris:
https://bugzilla.redhat.com/show_bug.cgi?id=815752#c5


With such config file modcluster crashed immediately upon start while parsing the local cluster.con.

GDB backtrace:

# rpm -q modcluster
modcluster-0.16.2-19.el6.x86_64

Fix should probably be the same as in ricci (attachment 648116 [details]) in bug 877381.

Comment 5 Jan Pokorný [poki] 2012-12-10 18:45:16 UTC

BTW., both modclusterd and modcluster (from the same modcluster subpackage)
are affected as they both link with the same culprit module.
