Hello,
Just in case it might be useful, I thought mentioning a similar
issue I had encountered in the past might help.
In my case, I had issues with the em(4) driver disconnecting from
the system while mbuf usage increased, so this may ultimately
prove be a separate issue.

Nevertheless, I figured mentioning it might possibly be of help,
since I ultimately figured out that the issues were caused by
me setting kern.bufcachepercent=90.
Setting it back to kern.bufcachepercent=20 fixed all my issues.
Through trial and error, I found that I could crank it up to 60%
without issues, which is where it's been since.
Again, my issue may be completely separate from the OPs issue, but
since both of them involved networking and the bufcache, I thought
I might at least mention it just in case it helps to reveal some
more information somehow.
