>Description:
The system crashes without any trace in the logs.
Finnaly it happened when I've been at the console and the message ws:
Panic: ufs_lock: recursive lock not expected, pid 112

syncing disks etc

automatic reboot

>How-To-Repeat:
The machine is a heavily used NFS server. about 30 machines import several directories from it
It only happenes when dealing with a large number of (I assume) large sizes.
For instance copying over a full directory tree, removind a directory tree, tar-ing from one place to another.
All of these on the NFS structure.
