zfs discuss - Nov 2009 - Kernel panic - directed here from networking

Hi,

I have been having problems with reboots, it usually happens when I am either
sending or receiving data on the server, it can be over CIFS, or HTTP, NNTP. SO
could be a networking problem, but they directed me here or to CIFS, but as it
happens when I''m not using CIFS (but the service is still running) its
probably not CIFS. I have checked for faulty RAM, ran memtest86+ (4.0), ran
through multiple times without problem.

The previous thread is http://opensolaris.org/jive/thread.jspa?threadID=116843

I have had 2 reboots today, within 10 minutes of each other.
The previous 2 crashes produced the following:

Any help on finding out the problem would be great.

Thanks
