4.8 crash while swapping heavily

[Calvin NG]

Greetings,

  Think I got that recently too, after cvsup and makeworld/makekernel
  (4.8-STABLE) recently on and around Aug 16.  Before that, last 
  makeworld etc. was in early Apr 2003.

  I do not have a trace, all I see is a kernel panic, and requires a
  hard reboot.

  I was using mfs quite heavily (1/3 of available memory) for this 
  server.  End up I doubled the phyiscal memory (RAM) I have on 
  this server, and so far its  okay for the past 3-4 days. (fingers crossed).

Regards,
