As per my previous messages on the list, I was having a strange problem in my test cluster (Hammer 0.94.6, CentOS 6.5) where my monitors were literally crawling to a halt, preventing them to ever reach quorum and causing all sort of problems. As it turned out, to my surprise everything went back to normal as soon as I turned off syslog -- special thanks to Sean!
The slowdown with syslog on was so severe that logs were being written with a timestamp that was several minutes (and eventually up to hours) behind the system clock. The logs from my 4 monitors can be seen in the links below:
I'm still trying to understand what is going on with my syslog servers but I was wondering... is this a known/documented issue?
Luckily this was a test cluster but I'm worried I could hit this on a production cluster any time soon, and I'm wondering how I could detect it before my support engineers loose their minds.
Thanks,
Sergio
