Resolution:
These error messages are generated whenever rvd or rvrd detect corrupted packets.  They are outside of the control of TIBCO Rendezvous and usually indicate that some network element is experiencing problems.

TIBCO Rendezvous software requires that the operating system compute packet checksums.  You must configure the operating
system to enable packet checksums on every host computer that runs RV programs or executable components.  

To determine whether packet checksums are enabled on Solaris, please run the following:

ndd -get /dev/udp udp_do_checksum

(If the result is 1, then checksumming is turned "ON")

TIBCO Rendezvous software requires that packet checksums are enabled at the hardware router level.  This is to prevent
RV from receiving any corrupted packets.  If the sender did compute a checksum and the receiver detects a checksum error,
the UDP datagram is discarded.
