Hi,
i'm not sure, if this could be a bug, but often concurrent access to my
beans lead to the following Exception:
com.evermind.server.rmi.OrionRemoteException: Transaction was rolled back:
thread 5 is waiting for resource entity 28417 in Site held by thread 6 in
transaction [Transaction 85:0:0:0:0:0:0:0:0:df:0:df:fc:c2:ea:4b] who is
waiting for resource entity 29185 in Site held by thread 5 in transaction

Nested exception is:

Is this a programming issue, that is, my fault? And if so, how do i get
information on what's going wrong? Or (as i hope ;-) should orion assure
that there will be no deadlocks of this kind? Note that i set the isolation
level to "repeatable_read".
Regards,
Jens Stutte
PS: My last few postings did not recieve any answer, if my questions are
stupid or annoying or if i should register (and pay) for further support,
please let me know.
