Hi Everybody,
We have a Jenkins instance that connects to a irc server over ipsec, the Jenkins server after running for over a week, ends up with about 300 OutputThreads for the irc-plugin .
The connection to the irc server is bit flaky , so it seems to get disconnected from time to time, our theory is that the OutputThreads are not getting interrupted after the connection is lost and re-established.
So everytime we reconnect another Outputthread is leaked.
When we take jstack dump on the jenkins process this is what we see below (I truncated the output to reduce the size of the email), please let me know if any further info is need to throubleshoot this issue:
Thanks in advance,
Luciano
