mpd locking system?

[Alex Povolotsky]

Hello!

for about 4-5 days, I'm expeirencing heavy troubles with my VPN (mpd) 
6.1-RELEASE based server.

After some time (minimum 2 seconds, maximum 12 hours) of running MPD 
with moderate load (about 100-200 clients, CPU not overused), system 
locks (even keyboard hangs) to reset. Nothing at all in logs.

Patching kernel to 6.1p12 did not help.

Attempt to add kern.ipc.nmbclusters="0" to /boot/loader.conf did not 
change anything.

The box seems to be healthy (at least, CPU fan works ok, no symptoms of 
overheating at all). It has run under more load without a flaw.

I hope someone can help.

Alex.
