Hi,

I have been noticing heartbeat stops for a couple of seconds (Collecting
daily information stats) and each time when the request is made to the
cluster during that short span of time keeps on waiting for the response. My
cluster is a two node cluster (active/active). How can i stop this behavior
and make my service even more reliable. This peculiar behavior happens daily
at 4:44 AM.
