ORA-12569 and ORA-12592

I have received two consistent Oracle errors: ORA-12569 and ORA-12592, and would appreciate your opinion on what may have caused them.

Oracle manual has only the following description:

>ORA-12569 TNS: packet checksum failure
>Cause: The data received is not the same as the data sent.
>Action: Atempt the transaction again. If the error is persisten, turn on
tracing and reexecute the operation.

>ORA-12592 TNS: bad packet
>Cause: An ill-formed packet has been detected by the TNS software.
>Action: Not normally visible to user. For further details, turn on
tracing and reexecute the operation. If error persists, contact Worldwide Customer Support.

Below are extracts from the SQL*Net traces I performed. I used nme.exe, set trace at ADMIN level. - first one from where ORA-12569 occured and second one from ORA12592. The full trace for the ORA12592 error code is attached with this message (file SQLNET87.TRC).

The traces are performed on a Windows 3.1x platform that uses SQL*Net 2.3, Q+E ODBC drivers, and accesses Oracle7 Server 7.2.2.3.0 over an IPX/SPX network.

Please reply by email to wai_at_OpenDataSystems.com I apprepriate any help provided. Thank you.
