Sam,
I'm also running the stock RELEASE kernel config- haven't had a chance
to do a rebuild yet.
But, I just noticed something interesting- the box has been running fine
for several days with multiple ssh connections, and several large remote
data loads (by way of postgres copy on port 5432). However, I just
installed webmin, set it up to run HTTPS on port 9090, and as soon as I
tried to connect- got the error. It does that every subsequent time too.
I will try the latest from 6-stable, but if you're thinking a big src
download from ports is high network io, well, lets just say the datasets
I'm copying around tend to dwarf the bsd source tree ;) (typically
they're several gb per dataset). So if that's still a problem I may be
jumping out of the proverbial frying pan and into the fire..
Thanks,
Bucky

The 'error mapping mbuf' error seems to have been fixed by the latest
set of changes to if_bce.c - after upgrading to the latest stable, that
problem stopped happening. =20
However, instead of that, under rather higher load, we now get the
watchdog timer error instead. This is not good :) I can get it within
minutes with something like building something big from ports, during
the initial source download.

I think moving to stable will fix the mbuf error for you, as that's what
others report. You, and all the other reports I've seen have been
running amd64, which I haven't been (I didn't build the box originally).
I'll know tommorow if amd64 makes much of a difference or not.
Oh, other info - I'm running the standard SMP kernel config with no
modifications.
Sam.
