Occasional heartbeat losses on R710?
Over the past few days, I've noticed that maybe every other day, my R710 seems to lose network connectivity. The CTL light starts flashing, and ZoneDirector says R710: Heartbeats Lost.
Upon investigation, it seems like I can ping the ZD just fine, but I can't ping the R710's IP. Eventually, the R710 initiates a reboot due to loss of contact and it comes back online just fine. I've tried replacing the cabling and moving the R710 to a different switch port. Doesn't seem to make a difference.
Are there any known issues with ZD 9.12.1 MR1 Refresh and lost heartbeats? It seems to be specific to the R710, as I've had the R700 on the exact same port and PoE injector with no issues for almost a year.
