Hi. I have two Dell 1750's webservers which I upgraded from 5.4 stable to 6.1 release (i386). I did the make kernel/world and rebuild the apps (mainly apache 1.3 and php 5) on one of them and upgraded the other one via nfs. The one I did the rebuild on, acquired a bad habit of just rebooting after 2-3 days whereas the second one just kept going. When they ran 5.4 I had no such issues. I once saw "bge resetting" in /var/log/messages so I added debug.mpsafenet=0 to /boot/loader.conf but that didn't help. I then removed the line and added vm.kmem_size=450000000 kern.maxvnodes=200000 which are settings I applied when the servers ran FreeBSD 5.1 through 5.4 (Scott Long's advise). Merging the three lines seems to help. hth Claus
