I am JBoss TreeCache in Spring. When I run unit tests. Everything seems fine. But when I
deploy the war file to tomcat, the following exception is thrown:
2006-09-27 15:33:00,321 ERROR [main]

Use either this or
desired_avg_gossip, but not both ! 0 disables it.
- stability_delay: range (number of milliseconds) that we wait until sending a
STABILITY message.
This prevents STABILITY multicast storms. If max_bytes is used, this should be set

Any hints about what is wrong?
