This seems like a network issue.
Might be related with the SQLNET.RECV_TIMEOUT and / or SQLNET.SEND_TIMEOUT set in the client / server SQLNET.ORA files..

Still, you need to trace a failing connection.. Level 16 Oracle Net works.. MOS Note : SQL*Net & Oracle Net Services - Tracing and Logging at a Glance (Doc ID 219968.1)
