Comment 1 Tomas Hoger 2008-10-17 09:16:38 UTC

Issue affects fence packages in the Red Hat Cluster Suite for Red Hat Enterprise Linux 4, and cman packages in the Red Hat Enterprise Linux 5.

Affected log file - /tmp/apclog - is no longer created by the current git version of apc fencing agents:
http://git.fedorahosted.org/git/cluster.git?p=cluster.git;a=tree;f=fence/agents;hb=HEAD

Comment 2 Fabio Massimo Di Nitto 2008-10-17 11:50:43 UTC

It also affects cman packages in Fedora9 and the whole cluster-2.03 release.
Backport from master will be available in the 2.03 series at the beginning of next week.

The 2.99.xx releases are also affected for fence_apc_snmp for all releases prior to 2.99.07 (not affected).
