Hi again Rainer,
It seems some of our software updates must have solved the issue, as it's
been working perfectly now for several weeks.
I think we may conclude that it didn't had to do with the the clustering
implementation.
I feel sorry that you put time into patching the issue. In case the
Thanks for letting us know!

Hi Rainer,
I'm sorry for the long delay in getting back to you.
I got sidetracked by another issue and wasn't able to look into this
earlier.
However, the bad news is that the administrators didn't allow me to apply
the patch as it is a production server.
I can apply it to pre-production, but

Hi Rainer.

I remember problems with clustering which were of the following kind:
session replication data was received on a node although the context
wasn't yet fully initialized.
Maybe we run into classloader troubles in that case?
This could only happen if another node in the

Hi List,
Maybe this is a very stupid question, but I am wondering whether a
ListenerStart of an application could be related in any possible way to
problems with the Tomcat cluster?
Thanks in advance.
Hi again,
I obviously meant ListenerStart Error.

listenerStart error will have a stack trace in another log file
depending on what version of Tomcat you are using.
That stack trace will take out the guess work of what actually went wrong

Hi Filip.
I'm using version 6.0.20.
You are not denying that the clustering could cause a ListenerStart Error,
is that correct?

Correct, not denying nor confirming. I'm informing you that your log
files would tell you what the actual error is :)

Hi, I'm back again.
I figured out why I got a ListenerStart Error, or at least, I got a nicer
error message.
However, I don't get it why my Tomcat servers start sometimes without
problems, and other times show the ListenerStart Error.
After restarting Tomcat a few times, the problem
