HI Martin, no changes which is odd. I can;t be certain 100% when this behaviour started. Perhaps when we changed to 7.8.0 a while back, but I'm pretty sure its only be happening the last week or so. Is this code basically saving all the sessions to disk on shutdown? Is this necessary given replication is configured as all sessions are replicate when it starts up?
