The "Send Buffers overloaded" error was added specifically for
overloaded binlogging to mysqld. The mysqld receives events
(data changes) from all DB nodes. Either the connections from DB nodes,
or the mysqld, or an attached replication channel cannot keep up.
In this case it would be the first one (DB events). Or else you
have found a new case for this error. Not sure if binlogging can
be disabled, others here will know.
Setting the buffer to 256M or higher does not help. It cannot
keep up, so it will soon be full.
