Hi,
I'm running a 4 node cluster and seeing the same exception as described in
this issue.
https://issues.apache.org/bugzilla/show_bug.cgi?id=51306
What can I do to workaround it or what can I information can I provide to help?
I'm running 6.0.32 with a securitymanager on Debian 5. Java version "1.6.0_22"
from debian sun-java pkgs.
My clusterconfig is this:
<Engine name="Catalina" defaultHost="xxxx.xxxx.xxxx">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase" />
<Cluster
className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
<Channel
className="org.apache.catalina.tribes.group.GroupChannel">
<Membership
className="org.apache.catalina.tribes.membership.McastService" port="47727" />
</Channel>
</Cluster>
<!-- Zorg dat de appBase regel direct na de 'Host name' regel staat -->
<Host name="xxxx.xxxx.xxxx"
appBase="/data/webapps/xxx-xxx/deployed"
unpackWARs="true" autoDeploy="false"
xmlValidation="false" xmlNamespaceAware="true">
</Host>
</Engine>
The exception from my catalina.out.
