loosing connectivity with jboss on ajp
--------------------------------------
Key: MODCLUSTER-179
URL: https://jira.jboss.org/browse/MODCLUSTER-179
Project: mod_cluster
Issue Type: Bug
Affects Versions: 1.0.3.GA
Environment: Windows server 2008
Apache 2.2.13 + mod_cluster
JBoss EAP 5.0.1
Reporter: Gregory Lardiere
Assignee: Jean-Frederic Clere
Fix For: 1.0.4.GA
During performance test of a jboss cluster (no session preserved) we issue some problem
with mod_cluster, specially when apache try to access to the jboss instance through ajp
And we don't see where the problem come from (JBoss configuration, mod_cluster
configuration, bug).
We don't use Multicast to discover nodes of the cluster
