The max_allowed_packet setting is the same on both.

I have tried restarting the slave... didn't work.  I can bounce the master.

Thanks,

Carl

First make sure that the "max_allowed_packet" setting is the same on both 
masters.

Make sure that setting is active on the slave in question.  Then start 
replication or bounce the master (not sure which I did to fix this the last 
time I ran into this).
