TNS-12656

Cryptographic checksum mismatch

Cause

The cryptographic checksum received with a packet of incoming data didn't match the checksum computed by the receiving end. This indicates that the packet was tampered with or otherwise corrupted in transit.


Action

Look for sources of data corruption, perhaps including deliberate tampering.
