I have an issue with a large delete transaction, on the postgres database there exists quite a bit of data and the query runs long.

I increased the timeout to 15 minutes, however the issue that happens remains the same. (I did this after searching for the error message generated by jboss). 

The error follows:

I hope someone has the answer, I'm out of ideas..  thanks for any assistance.
