Hello ,

I am using 7.0.2 version of TomEE. Intermittently , TomEE freezes . When I
reviewed the thread dump,it shows there are many threads blocked at DB. Not
sure if it is issue with DB or TomEE.

I am not sure if it could be an issue with network, Any property like query
timeout available on datasource level , which i can configure in tomee.xml
file ? I checked the documentation, but i haven't found any such property.
