Here a short info:
with the options MBUFTRACE i had the same problem one or two days
later (i mailed the logs). After that i increases
kern.mbuf.nmbclusters with options NMBCLUSTERS=16384. Now the machine
is running since 25 days and had served nearly 2TB without problems.

Donno if i solved the problem or just pushed the problem into a longer
timeperiod.

I will let the machine run long as possible and will give you the
result here.

so far Stephan Pietzko
