Leo,

Whether or not the server is remote or local has little to do with whether TCP/IP connections can have network problems.

The problem you're experiencing is because you've configured your connection pool to let connections remain in an idle state for longer than what the server will allow. The server reclaims connections that have been idle for quite some time, as it is a waste of resources. There's not a lot of situations where it makes sense to let connections sit idle for _hours_.

The fix for this is covered in the documentation:

For an example of a way of configuring a connection pool to not allow long idle times, see:
