Cause

What you are experiencing is outside of Autosys and something external is killing these connections.

This could be a firewall that is killing INACTIVE sqlnet connections after a set amount of time.

Resolution

Investigating the Oracle error ORA-03135 error message determined your issue to be network related with respect to firewall terminating the connection. Please have a look at the following Burleson Consulting URL which explains the error in more detail and provides suggestions for resolving this at database level.
