This problem happens when binlog is not enabled and there are statements for non InnoDB tables. Then, binlog events will be created for these statements, but they are never cleaned from transaction cache.
A simple fix is to prevent creating of binlog events for non-InnoDB tables. With this fix MEMORY tables will always remain node local.
Note that MyISAM replication (if wanted by wsrep_replicate_myisam), will still work through TOI replication, these binlog events would not be needed for that.
