Hi folks,
This one is driving me nuts. I'm testing out an iSCSI setup to provide VMs to vsphere. However under load, the FreeNAS system will spontaneously reboot. And I can't see any evidence of things like a kernel panic in /var/crash. (the only file there is minfree).
First I ran extended Dell diagnostics, and then memtest86. All passed fine. Eventually took the FreeNAS USB sticks and moved them to a known-good server. Same results. System reboot w/o evidence.
Which in my mind leaves a couple of possibilities:
mpr0@pci0:6:0:0: class=0x010700 card=0x30a01000 chip=0x00971000 rev=0x02 hdr=0x00
vendor = 'LSI Logic / Symbios Logic'
device = 'SAS3008 PCI-Express Fusion-MPT SAS-3'
class = mass storage
subclass = SAS
ix1@pci0:35:0:1: class=0x020000 card=0x00038086 chip=0x10fb8086 rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = '82599EB 10-Gigabit SFI/SFP+ Network Connection'
class = network
subclass = ethernet
Both systems are AMD-based multi-core (one server has 16 cores, the other 64) and have 256GB ECC RAM. FreeNAS version:
FreeBSD <HOSTNAME> 9.3-RELEASE-p29 FreeBSD 9.3-RELEASE-p29 #0 r288272+dc0354b: Sun Nov 1 18:57:19 PST 2015 root@build3.ixsystems.com:/tank/home/stable-builds/FN/objs/os-base/amd64/tank/home/stable-builds/FN/FreeBSD/src/sys/FREENAS.amd64 amd64
The questions I have at this point are:

Which in my mind leaves a couple of possibilities:
- One of the cards that is still in use with the completely-new server doesn't play well with FreeBSD and/or iSCSI
- Something is wrong with the FreeNAS installation / configuration

The questions I have at this point are:
- Am I looking in the wrong place for evidence of a kernel panic or other cause of a reboot?
- Does FreeNAS automatically reboot in case of a kernel panic? I get the impression that the answer is "no" based on:
[root@freenas] ~# sysctl debug.debugger_on_panic
debug.debugger_on_panic: 1 - Is there anything obviously incompatible with the hardware described above?
- Are there any other tips for where I should go from here?
