Error reported when starting app in cluster
Getting an ERROR reported when starting webapp within a cluster.
Note, at this time I am starting the first server in the cluster, which is
the 192.168.0.1 mentioned in the error message.
Can someone please explain if it is correct that I am receiving an error and
if so, what is wrong.

Indeed, using lsof and ps I found there was a 'ghost' tomcat instance
running. Killed that and all is well.

You mean this error is normal when starting the first server in a cluster?

No other problems reported.
This error appears at the beginning of the application's log then afterwards
it continues and starts the application without problem. I can then go on to
use the application.
Haven't tested whether session replication is working yet, but this doesn't
inspire confidence.
Sounds like it is not normal to see this, so will check my cluster
configuration.
Cheers,
D.

Does this application run well in a tomcat that isn't clustered?
Does your application have the <distributable/> element in web.xml?
Having gone through something like that as well, a while ago, I'd
recommend looking through the output in the other log files in
$CATALINA_HOME/logs/, especially localhost, to see whether there are
any exceptions / errors reported that might keep your application from
comin' up well.
Cheers,
Kristian
