Check for firewalls between the appserver and the database server. The
error is a TCP-level connection error that means that the peer (the
database server) unexpectedly disappeared on us, and we didn't see an
orderly shutdown of the connection. If it always happens after a certain
connection length, or after the connection has been idle for a certain
period, it's likely that there is a stateful firewall in the way that is
dropping the connection after that period.
Failing that, does the database side log anything about the disconnection?
