Bruce,
Please do us a favor, these kinds of reports basically go into the
bit bucket when posted to the freebsd-questions mailing list.
If you would be so kind, please run send-pr on your 4.11 systems
and send what your seeing in as a bug. Granted, since it's not
specific nobody is going to be able to send you a patch or some
such - but there is still value in these reports being in there as
if others report the same trouble a coorelation can be drawn.
Also please list the model number of your SuperMicro motherboards.
Thanks!
Ted
Supermicro motherboard X5DPR-8G2+
It has been running 4.11 solidly for almost 2 months now.
Some more info on the system is here (about a problem experienced
on the same system):

I applied that towards the end of January. Pretty sure anyway,
memory is fading.
We were running:
FreeBSD 5.3-RELEASE-p5 #3
when we abandoned ship. If memory serves, I rebuilt the kernel
only (not the world), when I applied those patches.
I have left the department that owns the server now, but
I've asked them to followup to this mailling list when they
continue with the diagnosis.

Subject: Had to revert from 5.3 to 4.11
Upgraded a large e-mail server from 4.7 to 5.3 late December/2004
The 5.3 system never stayed up for more than 3 days (kernel panics
- often while running vacation).
A fair bit of fiddling trying to keep it running for about a month,
then gave up. Kept the kernel tree updated, no difference.
Reverted to 4.11 about 3 weeks ago, no problems since.
Also upgraded a web server to 5.3 during that time, and
had to retreat also, same reasons.
We do have a heavily loaded 5.2.1 system running well.
Main difference between the crashy and reliable system
is nfs home dirs on the mail and web servers. nfs server
is 4.7
Same hardware in all cases, dual xeon supermicro.
At a later time we will invest further diagnostic effort.
Sorry for the lack of specifics.
