Subject Re: Recurring snapshot taking full every time
Date Mon, 14 Sep 2015 10:30:00 GMT
Looks like the host is not instrumented properly and management server is unable to invoke
plugin on the host.
Can you force-reconnect the host that is throwing this error ? That should recopy the plugins
on to the host.
