Suddenly I get FATAL TRAP 12: Page Fault while in Kernel mode

[PhoenixWeb]

I get this every few minuts and the system reboot few seconds later (due to watchdog).

Code:

Fatal trap 12: page fault while in kernel mode
cpuid = 5; apic id = 05
fault virtual address = 0x7c
fault code = supervisor read data, page not present

....
....

Stopped at   udp_notify+0x72: movl   0x7c(%rdi),%eax
db:0:kdb.enter.default> write cn_mute 1
cn_mute   0  = 0x1

After this I tried to solve:
1) by to upgrade to FREENAS 11.1
2) move all disks to a twin server with same configuration

But the issue still happen.
Seems to be connected with an issue of networking.
However seems impossible that a kernel crash iwith a UDP packet.

I have many data that I really really need to rescue and put it online.
Please help.

Thanks!
