Re: Semi-sync replication hangs when changing binlog filename.


The process list shows that the query is blocked waiting for back from semi sync slave. I can post further information shortly, AFK currently.

By "binlog filename changes" you mean when master starts writing
binlogs into a new file?
Can you clarify how the replication stalls? What "show processlist"
shows at that time on master and on slave? What does "show slave
status" show on the slave?
