Hello All,

********
This is not a doubt, it's just a report of a problem that I had and solve it after hours!
This is just in case someone pass thru the same error!

I have a SFSB on my project that inserts records to my database from a uploaded file.

My session timeout is huge. When I use a file with many records to import (more than 5 minutes making database operations) I get this error:

22:15:56,250 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_58] - Abort of action id -3f57fe87:dd1e:478d4a9e:49 invoked while multiple threads active within it.

I changed the transaction timeout at jboss config and everything worked good:
(/server/default/config/jboss-service.xml)

 <!-- The default was 300 seconds -->
 <attribute name="TransactionTimeout">1000</attribute>

Thanks.
