A truss suggests it might be hanging on the NFS mount I have on an old NetApp. It does NOT hang with simple "ls /netapphome" but does if I use "ls -l /netapphome". I had hooked up the NetApp last week but had some problems, so I left the mounts in place. But it looks like some "ls" I did on those mounts last week are still stuck (Thu11AM above must be from last week because it's 10am Thursday now).

I can't reboot the troubled box right now because I've got a bunch of network connections going that need to stay. Any suggestions to help diagnose this? should I do a send-pr on it?
