Hello, today my team reported that one of our PE1950 servers with ESXi 5.5 started to reboot unexpectedly 4 times, and after the 5th boot, it stopped rebooting.
I got the following summary of logs from the vmware-support tar file , from today (Nov212016 UTC -5):
1) vmwarning:

Searching in google, i suspected that the issue could be related to this bug: ESXi 5.5 host server reboots unexpectedly followed by Uncorrectable Machine Check Exception error (2..., however, I didnt find the specific UMCE error. So, I dont know which could be the cause of this behavior.
I also suspect that the server could shutdown because of high temperature on room, or error 1215 on server screen, but this error only refers to a voltage level.
Any idea of this behavior' root cause is greatly appreciated, since often the esxi logs are not conclusive.
Regards.
