FreeNAS 8.03 Crash after being up for about 20 mins

[nickhalliwell]

I have this version of FreeNAS: FreeNAS-8.0.3-RELEASE-p1-x64 (9591)

I am running FreeNAS on an Asus M5A 78L-M LX mother with an AMD Athlon(tm) II X2 260 Processor CPU, I have 8 GB of RAM. The mother board has an inbuilt Intel graphics card. I have updated the latest BIOS on the MB to 0801. OS Version: FreeBSD 8.2-RELEASE-p6

I have 4 x 500 Gb WD hard disks. Running in ZFS RAID (equilivant to RAID 6.

Its all set-up and works, I have set up ZFS data sets and CIFS shares. All machine can access all the drives. I have Windows 7 PC and Ubuntu Machines

However it crashes once it be running for a short while. I cant see any error messages as the Screen becomes unreadable. I cant give any more detailed information as I does not appear to happen to any given event or schedule.

I can access all configuration items from the Web browser, but once it crash's then even that is dead. I cannot see any error massages.

The other thing that is odd, is that the Time zone is correctly set ie Asia/Bangkok?. But the time shown on the running tasks screen and the system information screen is always 5 hours behind. The time is correct on the hardware.

I attach a the Debug output View attachment debug-freenas-20120201113831.zip

you most likley have a flaky hardware.

Investigate among 2 routes :
- login through a terminal and examine /var/log/messages ther is probably information here
about trouble
- boot up memtest86 and have it running for a few hours ( easiest way to obtain is to download and boot
a ubuntu-distribution, memtest is one of the boot-choices)

Are you having kernel memory starvation (kmem panics and the kernel dies from memory exhaustion)? Check your /var/log/messages to see what it says. User "Protosd" has a separate website with an FAQ, look at his response to question 22 for how to allocate kernel memory.

In my experience, memtest86 will tell you within 1 hour if your RAM is bad. You can directly download an ISO for it the last time I checked.
