It is funny, now that I want it to crash, I am having trouble.
See the end for details.

I run FreeBSD 3.1 Release
X-Free86-3.3.3.1
Netscape-navigator-4.5
On a 75 megahetz Intel pentium
with 40MB of RAM
and 80MB of swap (Normally mounted on /tmp as a mfs)
I only got the system to dump once. I enabled "dumpdev="/dev/wd1s2b" in
/etc/rc.conf. (Dumping to my 80MB swap partition) I rebooted and pushed the
system to panic by a short jaunt of web surfing. It went through a coredump,
numbers piled up on the screen, and finally a message that the dump had
completed sucesfully.
When I rebooted, the savecore was detected. It listed the time, date, and
the reason for the dump. (vinval buf: dirty bufs) But on the last line it
said that the dump was unsucessful "not enough free space on device" Would
my dump really be more then 80MB?
As I said before, I normally have my swap space mounted on /tmp as a
memory file system. I wondered if the mfs was responcible for the unsucessful
dump. So I removed it from /etc/fstab and rebooted.
Since then, I have not gotten the system to panic. It haven't had time to
put it though a terrible stress test, but it normally paniced on less then
I did in my tests. Could the removal of the mfs have fixed the problem?
Either way, I am probably doing something wrong when I try to do a savecore
dump. I will have to look into that later. In the mean time, does any of
this info help?
