No, no snapshots are taken. As said this is a spurious event which has
happened at 03:56 for the past two nights. However, we ran for a few
days before then with no problems. Before that it happened at something
like 5AM. It does not happen every night, nor at the same time
(usually).
I have set up a couple of cronjobs to check ifconfig and ping the
interface every few seconds. I also have a job that will monitor the
main interface for VRRP traffic since that should show what the priority
value is when a server claims to have received a higher priority from
another server.
