In the logs for a machine:
vm_fault: pager read error, pid 26656 (valtest)
vm_page_free: freeing wired page
Apr 22 20:40:00 monica /kernel: pid 26656 (valtest), uid 2436: exited on signal 11
...
...
Apr 22 21:11:32 monica routed ....
panic: vm_page_unwire: invalid wire count: 0

It seems obvious the 3 messages are all tied together.  What would cause the 
first (whihc is the apparent cause of the other, and the final panic).  
There is no mention anywhere in the logs of mechanical difficulties.  The
swap disk is a <Maxtor 84320D4>, DMA, 32-bit, multi-block-16>.

(the other messages ahre there just to provide a time context for when this
happened.)
