Ben's notes

If PowerDNS is crashing with the following message

Exiting because communicator thread died with error: 
GSQLBackend unable to refresh domain_id 3: 
Failed to execute mysql_query, perhaps connection died? 
Err=1: Binary logging not possible. 
Message: Transaction level 'READ-COMMITTED' in InnoDB is not safe for binlog mode 'STATEMENT'

You can fix this with:

 mysql> SET GLOBAL binlog_format = 'ROW';
 

The error arises only if the binary logging option, which is required for the replication, is turned on for the MySQL server.
