Hi

in a 5.0.45 linux master-master replication setup, I see the error 
message from the subject every now and then. Sometimes it does not 
happen for a couple of months, then it happens a couple of times a day. 
I cannot see any network problems otherwise, and a memtest did not bring 
up any memory problems. It "feels" like this happens on a rather high 
load on the system, as it never happened at night.

What can I do about that?

Regards
Dominik
