Hi!


I just checked out the new changes to BRANCH_1_3


The problem with deadlocks has not gone away - but the problem is not as persistent as before
- and only occurs once in a while.


I have seen the problem on both client and server.


Sandesha is setup to resemble the MS sync RM 1.0 implementation..



The problem seems to occur the same place on both client and server :



org.apache.sandesha2.storage.SandeshaStorageException: Sandesha2 Internal Error: deadlock
