Subject Re: CS 4.5.2: all hosts reboot after 3 days at production
Date Mon, 07 Sep 2015 20:18:59 GMT
Hi Vadim,

What kind of storage do you use? Can you show /var/log/xha.log (I think that is the name)
please? It could be xen-ha that fences the box if the heartbeat cannot be written. 

You suggest it is CloudStack. Did you see anything in the mgt logs?

Regards, Remi
