>How-To-Repeat:
cant exactly also repeat it cause it locks on many different programs.. 
its only been since i just upgraded to 4.6-stable on a few machines.
it happens especially often if i set maxusers to 512.. happens less often if i set em to 0 for auto scaling..

 You should set dumpdev="/your/swap/partition" in /etc/rc.conf, rebuild 
 your kernel with "makeoptions     DEBUG=-g" and after next crash analyze 
 /var/crash/vmcore in order to provide more detail.
