I have a server (HP ProLiant DL380 Gen9, Intel Xeion CPU E5-2609v3 with 2.04 TB) running VMWare ESXi 5.5.0 with 2 VMs. I've been having issue of sudden reboot every once in a while. I've gone through VMware Knowledge Base (Determining why an ESXi/ESX host was powered off or restarted (1019238)) but nothing comes up.
I guess my question is - can I get some sort of hint in the vmksummary or vmkernel log files to find the issues ? I've gone through those files but nothing pops-out of the ordinary before the reboot happens.
What are the places to look in the log files ?

2018-01-29T16:34:37Z bootstop: Host has booted
from the vmksummary, it shows that the host is booted and coredumped as per the logs.. This indicates a hardware specific nature of issue or an ASR
If it is user initiated then it should list host is booting first and then host has booted
