Description george 2001-04-25 15:50:01 UTC

Under high throughput NFS, our webserver process (thttpd) consistently hangs in vmopar or objtrm.
The process get's stuck, can't be killed, and the machine must be rebooted.

How-To-Repeat: Run thttpd mounting an NFS doc root.  Generate 10-20Mb of sustained web traffic and start changing files on the shared mount point.

This PR should be open. 

Some vmopar hangs were fixed for the 4.2 release of FreeBSD, but 
some still remain. It is probably worth upgrading to 4.2 or 4.3 to 
see how much your situation improves.

Many NFS fixes were recently committed to 4.4-stable.  Please 
update to the latest version of the -stable branch and see 
if the problems you encountered still exist.
