What kind of file system are you guys using?

I'm thinking there is a dead-lock in somewhere in the
system.  If I was runnig top on another TCP connection, I
saw like 240k free space whenever machine locks up.

I have this kind of lock-up in following
situation/configuration.

 - 1.6.1 software RAID5 using ffs and
   1.6ZC hardware RAID5 using ffs w/ softdep
   doing "tar cf - | (cd xx; tar xfp -)" over network.
 - 1.6ZC software RAID5 using lfs
   doing "iozone -a"

I ended up to use 1.6ZC with hardware RAID5 using ffs.
