Hi Shreedhar,
Thanks for your reply. The stackstrace has nothing except the warning:

This is happening only when I am running two instances of Glassfish running
on the same machine. One instance is Glassfish 3.1.1 and another is Glassfish
2.1.1
Are both instances trying achieve lock on any particular file ? Please let me
know if you need any more information
Regards
Arnab
