Subject Continuous Ping query caused exception: java.util.concurrent.RejectedExecutionException
Date Thu, 01 Nov 2012 09:39:45 GMT
Hi,

Using this week's trunk we sometime see nodes entering a some funky state where it continuously
reports exceptions. Replication and query handling is still possible but there is an increase
in CPU time:

This won't stop until i restart the servlet container but began in the first place after restarting
the servlet container. Any hints to share? File bug?

Thanks,
Markus
