I have never heard of this issue, HOWEVER, read below:
Last weekend we had a BAD thunderstorm roll through where my WISP is located in Lancaster PA and a Tower (Bareville Water Tower) went down in the storm.
Thinking the worst I drove out expecting to see some carnage but all we had to do was reboot the switch, no damage was done but obviously the thunderstorm did something the switch did not like.
The switch is still in service running great. See picture below of that switch which we rebooted 5 days ago (last weekend).

Was there a storm in the area?
Next time this happens (if it happens) console into the switch and see what's going on.
Now my switch that I had to reboot after the storm was locked up tight so I could not console into it.
However I was impressed that whatever it was that happened in that bad ass storm the switch held up only requiring a reboot. Now that is not to say they will always survive thunderstorms, bad things happen in storms especially if not grounded well and your tower ground is not bonded to electrical service ground which WILL cause fried Ethernet ports!
It was a NASTY storm with wind gust of 45-50Mph and dark green to black skies lighting up about every 10 seconds.
Yea I know I need to upgrade the firmware, but this is a low priority tower and I forgot about it and as you can see this is an OLD RevB board (we a re now on RevD on production units).
