Every three - four days we are getting a JBOSS server failure. The sun.misc.Cleaner code terminates shortly after 3am with the following error:

JBoss shuts down completely !! Having researched this it appears that this was a feature added to Cleaner in later releases in the advent of failure
This happens on two out of three cluster members. The third remains up and running.
Is there any way we can tell what is actually making the call to cleaner around this time without recompiling the cleaner code or can anybody shed any light on what is going on ?
