PROBLEM WITH BPEL  USING JBPM_TIMER WHEN JBOSS IS RESTARTED

Mohammed Afzal Newbie

Hello,

I am using a BPEL process which has a PICK element with <onAlarm for="'PT15M'">. Once process is intiated the BPEL process inserts record to JBPM_TIMER table with appropriate DUEDATE_. Under normal circumstances the process runs fine. But if process in not completed with record still in JBPM_TIMER , and I restart the Jboss application server the next time when the pick wakes up on timer I get the exception from Hibernate saying that deadlock situation in database. I am under impression here the jboss is caching the timer in memory and trying to update two timers.

Here is my environment and exception stackTrace any help is appreciated.
JBOSS : 4.0.3 SP1
DB - SYBASE 12.5
JBPM_BPEL -- BETA 2

thank you
Afzal
