To reproduce the problem run around 10 copies of cp -Rp /usr/some-random-dir. All cp's after some time are hanging on getblk. du's running concurrently are hanging in ufs state. The filesystems are UFS2. The Server is running 5.2-BETA on SMP Dell 2650. Filesystems are laid on Adaptec RAID controller (aac). Any ideas how to trace the problem? /S
