REPLA in log file

Hello,

We have a three node XtraDB Cluster, and we are experiencing slowdowns and some other problems with it. We are not sure if the cause of the problems is the database itself, but usually, before something goes wrong there are multiple lines in the mysql.log file with just REPLA in them:

REPLA
REPLA
REPLA
REPLA
REPLA
REPLA
REPLA
REPLA
REPLA

What causes these messages?

Thank you for any insight

I have not seen those messages before and I cannot see anywhere in the PXC or Galera source code that prints such a message directly. I’d suggest filing a bug for further investigation: http://www.percona.com/doc/percona-xtradb-cluster/howtos/bugreport.html

I have a lot of those mysterious entries in my syslog too, just before mysqld crash…

My software version: mysql Ver 14.14 Distrib 5.6.21-70.1, for debian-linux-gnu (x86_64)

Thank you for any advise
