We are having a similar problem at the job I just started. A box meeting
the exact specifications that Mike said caused the problem is essentially
having the crap beat out of it as far as disk access and network activity
(it might help to also say that this company is rather large in the scheme
of things and would be a good example of how to use FreeBSD in a large
enterprise environment). It is the only box out of alot of them having
this problem, but its also the only one thats getting beat up as much as
this one.

it would be great if Peter could post his "patch" for the problem (how to
migrate the -CURRENT driver into the 3.3 source) from what you say, Ed, it
stands up a bit better than the current driver does, and can only probably
get better. While this machine will probably be replaced with a different
machine, FreeBSD is somewhat of a "Pride and Joy" here. 

-Pat
