Any chance you can get the memory usage at that time?

I have updated to 10.1-RC from 9.2 and found trouble with wired memory
increasing, when 7G is wired out of 8G, starting new processes fails at
which time I need to reset. I have been unable to get uptimes of much
more than a day on my desktop machine. zfs compression seems to play a
part, which might mean the same zfs changes to 9.3 and 10.1

I found that constant simultaneous disk writes can re-produce this
within minutes.
