ESXI 5.1 CRASH

[Digfut]

Hello,

This is my first post in this forum, sorry if my english is not very good.

I have a ESXI 5.1 server (HP SE316M1/DL 160 G6) with 3 virtual machines, it has been working perfectly for more than a month. Server has 16GB RAM, 14GB for the machines and 2 GB left for the host.

Since last Friday I got 3 issues where virtual machines where unresponsive (although they appear as running on host), host was working and I was able to manage it through SSH and client.

After a reboot all is running correctly.

This has happened 3 times in last 4 days.

No hardware issues are found in ESXi report.

No RAID controller or drives issues found in hpacucli report (my controller is HP Smart Array P410).

I checked vmkwarning.log and found these lines at the time of last incident:

What would explain that host works perfectly and all 3 machines stopped responding at same time? they appear as running on host panel. If it was a hardware issue (memory, processor, disk...) then host would hangs too, right?.

Can you shed any light on this?, this is a production server so I´m very worried.

Regards.

Right.If it was a hardware issue (memory, processor, disk...) then host would hangs too.Did you check the VM guest OS event logs?

OK, how about try to apply the latest firmware from HP SPP 2015.06 and then update the ESXi 5.1 to the latest Update 3 ?

I've done this ti rectify the PSoD on my HP servers most of the time.
