Client generated an SQL query.

The packet checksum field (in the header) is non-zero.  The program is used to this field being zero.

Invalid packet length in TNS header. The length should match the wire length, and should not be greater than 8155.

"Current packet does not have a TNS header"


Any ideas?  I've never seen this before.
