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
- 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.
