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. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194654 -- FreeBSD - the place to B...Scaring Daemons Shane Ambler
