Packet writer failure

I am getting this error: "ORA-12571: TNS:Packet writer failure." The problem does not happen all the time. The sqlnet.ora file only says "sqlnet.expire_time = 5."

I am getting this error: "ORA-12571: TNS:Packet writer failure." This is on an HP Unix server HP-UX B.11.11 U 9000/800 with Oracle9i (9.2.0.1). The problem does not happen all the time. The sqlnet.ora file only says "sqlnet.expire_time = 5."
This error message usually indicates something is interfering with TCP/IP messages between the client and database server. This particular error is sometimes seen when there is virus scanning software running on the database server. You should also check that the network card on your database server is functioning properly. Finally, you may want to experiment with increasing the value of sqlnet.expire_time in the sqlnet.ora file.
