| Subject: | Shutting down one server, creates a new logfile every few seconds![]() |

Description:
When one of the servers in a replication scheme, where master = slave of
master,
goes down, the servers replicate eachothers 'set logfile' command.
This results in a new logfile being created every few seconds and tying up
server
resources.
How-To-Repeat:
1) Set up a tipical replication scheme, where the master of x is also the slave
of x and vice-versa.
2) Make sure replication is working.
3) Shutdown one of the servers.
Notice, the number of logfiles in the logdirectory.
I am unsure if this is related to the use of the
log-bin=/path/to/logdir/logname directive.
Fix:
Work-around: stop the slave, before a shutdown. This is only a marginal
work-around, cause if a server
crashes, for whatever reason, this can also happen.
