But the solution is not very simple because you might think it could help to increase the time-out value (conf/jboss-service.xml). It doesn't. Somehow this value is not taken into account. And i am using Hibernate for the persistence, and i did not find a way to influence the time-out settings of a transaction programatically (the normal transactions can, but hibernate hides or disables these functions). So, i have reprogrammed the 'heavy pieces' of software. All intense calculations are performed before any transaction and that seems to have solved my problems.

I think the reason that editing that file is not sufficient is that it may not be persisted across restarts.  I found from some other research that if you want to change the timeout setting across restarts, then:

You can edit the jboss-service.xml file in server/conf/templates to
persist values across restarts.

I haven't tested this myself yet, however.
