FreeNAS crash, have to manual reboot

[soulaero]

My FreeNAS crashed this morning again, on consolo, I can input 13 (roboot), then 'enter', but system just hang on, no any response then. I have to reboot it manually. System has an issue at around 09:00:00, I rebooted it at 09:28:46

There is no any related logsin /var/log/messages,

There is no dump files in /data/crash.

Since it has happened more than twice, what can I do to detect the issue? Freenas version is FreeNAS-9.3-STABLE-201602031011

If its hanging, that's not a crash. A crash is a kernel panic, which you aren't getting. So claiming it is a crash is incorrect.

I'm betting you have some kind of ACPI issue. Can you post your hardware specs?

It's a HP DL 120 G7

CPU: E3-1270
MEM: 12GB
Harddisk: 4* WD20EARS , 2*2 Mirror


Yeah, I'm not sure if it's an hardware issue.

Yeah.. can't help with that. No experience with HP on FreeNAS.
