ORA-12571 - What to do?

What to do if the Oracle-Error 12571 is coming up regularly ??

We are running Oracle 8.1i on an NT-Server 4.0 SP6.

All our measures were only a short time success.

ERRORs

primary error

ORA 12571: TNS: packet writer failure

Cause: An error occured during data send.

Action: Not normaly visible to the user. For further details, turn on tracing and reexecute

the operation. If error persists, contact worldwide Customer Support.

secondary error

ORA 03114: not connected to oracle.

Cause: A call to oracle was attempted when no connection was established. Usually this

happens because a user written program has not logged on. It may also happen

if communication trouble causes a disconnection.
