But the odd thing is that it doesn't throw it everytime, but with some cases, and locally the same cases work fine and also most of the cases are those when the time of the function to return the data is higher... Can someone plesae help me, find out why? and how to stop it?

How higher? It might be possible that the active transaction times out but I would expect to see it somewhere in the logs. Do you see any transaction timeout message before this error? You should be able to set the transaction time out time somewhere...possibly in the datasource definition.
