Given time, the ZIL seems to 'catch up'. The more processes running to = ZFS, the faster it seems to hang. The actual amount of data seems to = matter less than the number of streams. Putting the ZIL on a seperate disk/controller has kept the hangs from = happening for me.

I'm running current as of 20080130 on an amd64 box. I can make processes stuck in zfs->io_ (output truncated in ddb and top) when I make some packages via ports tinderbox. The ports tinderbox access local disk via nfs (I also tried nullfs). ddb output of ps and alltrace can be found at http://www.rafan.org/FreeBSD/zfs/textdump.zfs.20090130.txt Any ideas?
