I request assistance gathering more details from a persistent crash I am seeing on my setup in hopes of finding a solution or submitting a helpful bug report.
I have the following setup
Recently, I added the sabnzbd and sickbeard plugins. Both work, but ended up causing what looks like the same crashes I had received when running the CIFS shares in rw mode. After debugging, I can run the sabnzbd plugin just fine - downloading anything is no issue. It appears to be the sickbeard plugin that generates the crash, specifically the process that scans for completed downloads, copies to the media directory, and renames them. This does not operate over CIFS/SMB, but instead uses the mounted pool through the jail storage for direct file access.
Crash details: (As many as I can get - help requested for more)
May 4 15:52:28 freenas kernel: Fatal trap 12: page fault while in kernel mode
May 4 15:52:28 freenas kernel: cpuid = 0; apic id = 00
May 4 15:52:28 freenas kernel: fault virtual address= 0x48
May 4 15:52:28 freenas kernel: fault code= supervisor read data, page not present
May 4 15:52:28 freenas kernel: instruction pointer= 0x20:0xffffffff81b133a0

May 4 15:52:28 freenas kernel: = DPL 0, pres 1, long 1, def32 0, gran 1
This is what I get repeating over and over for a few minutes in the console until the machine restarts:
I have since disabled the sickbeard jail and remain in readonly CIFS mode
Things I have tried:
I have the following setup
- FreeNAS-9.2.1.5-RELEASE-x64
- Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz
- SuperMicro X9SCM-F
- 24 GB ECC RAM
- Intel Pro/1000 NIC
- raidz2 - 6 x 3TB Hitachi
- raidz2 - 6 x 3TB Hitachi
- raidz2 - 6 x 2TB Seagate
- cache - 240GB OCZ SSD

Things I have tried:
- Updated from FreeNAS 9.2.1.4 (where I started)
- Change SMB min and max to 2.0
- Enable debug kernel and check /data/crash - no files
- Services: CIFS, iSCSI, NFS, SMART, SSH
- Memory utilization does not peak prior to crash
- Running FreeNAS on SanDisk Extreme 16GB USB3 drive (internal USB 2.0 port on MB)
