The default JBoss transaction timeout is 300 seconds. This may be too short for your purposes, particularly if you have a large catalog.

To increase the transaction timeout, edit the <JBdir>/standalone/configuration/server-name.xml file and find the configuration for the urn:jboss:domain:transactions subsystem. For example:

<subsystem xmlns="urn:jboss:domain:transactions:1.3">
   <core-environment>
     <process-id>
         <uuid/>
     </process-id>
   </core-environment>
   <recovery-environment socket-binding="txn-recovery-environment"
     status-socket-binding="txn-status-manager"/>
   <coordinator-environment default-timeout="300"/>
</subsystem>

Change the value of the default-timeout attribute of the coordinator-environment element.
