Server restarts about twice a day

[darwinsurvivor at gmail.com]

My FreeBSD server has been crashing 2-3 times a day with the same error. It
appears to be ZFS related and it started happening after I did some updates.
Until then, the system had been running flawlessly for months at a time.

OS: FreeBSD 10.0-RELEASE #0 r260789
Filesystem: ZFS (encrypted root)


I am not certain of the times of the crashes as they tend to happen when I
am
not using it. I did get the timestamp of the most recent though (11:20am).

I have manually run the cron jobs scheduled for around that time but nothing
triggered the crash.

Of the last 10 crashes, they all generate a core.txt file of roughly 9000
lines.
Oddly, one of them, core.txt.4, was just over twice that size. I have
attached core.txt.5, which is the most recent (core.txt.4 is too large for
the mailing list).


I'm much more familiar with Linux's debugging tools than those of BSD, so
any
help would be greatly appreciated.
