I have a 6.0 system running on a P3 550 that is rebooting every now and 
then due to a trap 12 error.  I've followed the steps at 
for getting a crash dump but I'm not getting dumps.  Here's the relevant 
line from rc.conf:


And it seems to be OK as dumpon has no problem when I set this manually:

blacksheep# dumpon -v /dev/da1s1b
kernel dumps on /dev/da1s1b

My swap partition is 750 MB and the total system memory is 384 MB.  Any 
ideas on what I might be doing wrong?
