Description Fritz Heinrichmeyer 2000-06-05 15:10:00 UTC

	sporadic reboots when imapd or smbd activities occur.

Fix: 

don't use SMP :-(
How-To-Repeat: 
	boot server with SMP kernel when samba and imapd users are active

Comment 1 Fritz Heinrichmeyer 2000-06-06 13:36:04 UTC

today i tried to make a crashdump for debugging, but i used
unfortunately the same kernel in single user mode to save the image. I
followed the advices in the handbook and typed

fsck -p

in single user mode. After checking the root fs it rebooted immediately.
Now the server has to do its work again, no change for debugging so far
...

The crash came after 40 minutes uptime when trying to read email with
the uw-imap daemon.

Greetings

Hello,

we moved the harddisks to an identical SMP-box. Now i wait since 5 days
for my spontaneous reboots at the new box.

After changing CPUs at the suspected box, one time only one was
recognized ...

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?
