If you have a baicells enb plugged into one, they will sometimes cause a broadcast storm, like a single port loop, if that makes sense, this causes a kernel panic and reboot. Things are really weird until you do a clean reboot. Mikrotik support can verify if this is the issue from the supout file.

It's just strange that these have been deployed for Months, but 2 locked
up in the same week. And 5 days apart, with different firmware, both in
temperature controlled indoor racks. I don't think it was triggered by
some rogue WAN Packets. If that was the case, I'd expect they both
would have locked up at the same time. MRTG showed no change in RAM
usage, or CPU prior to the lockup.
