Hi,
We have 3 Free BSD 4.0 Servers with Ultra160 Adapatec Cards, and ccd'ed U2W drives.
They each serve about 500 Pcs (NetBSD), using nfs. Most of the use is from students editing and
compiling files.
They are heavily used all day (and night) long.
The problem is that some times (1 or 2 times every 24 hours), the nfsd process stop in inode state.
The Os is still working. i can log on the pc but can't kill the nfsd processes.
Sometimes the file system which NFS is exported is unavailable, and unmountable.
And we get a fsck of our exported File system.
Her are some of our servers confs:

ad2: 19574MB <IBM-DPTA-372050> [39770/16/63] at ata1-master using UDMA33
ad3: 19574MB <IBM-DPTA-372050> [39770/16/63] at ata1-slave using UDMA33
