>Description:
FreeBSD reboots alone with no reasons.
nothing appears in the log files except in the last command:
reboot           ~                         Wed Jul 17 15:01

i have this problem with different computers, under freebsd 4.5-RELEASE and RC1. one with SCSI-RAID1 (adaptec 2110), 2 with IDE disk. p3-1Ghz and 512MB ram. installation: standard-recommanded + rebuild of the kernel with the following options
maxusers        512
options         NMBCLUSTERS=65536
options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_DEFAULT_TO_ACCEPT

sysctl options i modified:
vfs.vmiodirenable=1
kern.ipc.maxsockbuf=2097152
kern.ipc.somaxconn=8192
kern.ipc.maxsockets=16424
net.inet.tcp.rfc1323=1
net.inet.tcp.delayed_ack=0
net.inet.tcp.sendspace=65535
net.inet.tcp.recvspace=65535
net.inet.udp.recvspace=65535
net.inet.udp.maxdgram=57344
net.inet.icmp.icmplim=300
net.local.stream.recvspace=65535
net.local.stream.sendspace=65535
kern.maxfiles=65536
kern.maxfilesperproc=32768

(the other computers with original sysctl parameters)

computers are running with apache 1.3.26, php 4.1.2 and mod_perl 1.27.
open ssh 3.4, ucd_snmp 4.2.5

i tried to remove the linix.ko module, but the computer rebooted again today. 
it doesn t seems to be because of the bandwith used on those computer (reboot occured with  1 or 5 mb/s of traffic, at different times of the day)

i don't know what to do to stop this, neither where to look because there is no logs...

thanks for the help

 I'd suggest that you try enabeling crash dumps by setting
 
 dumpdev="/my/swap/device"
 
 in /etc/rc.conf. You'll need a swap device which is atleast as big
 as the amount of memory in your machine. After this, the next time
 it reboots see if you get a crash dump or any more useful message
 in the logs.
 
 If you don't get something more informative, then the chances are
 that the problem is some sort of hardware problem. If you do get a
 message when we have a better idea what is going on.
 
 	David.

 6 days with no reboot ...
 and i had 1 or 2 reboot each day.
 
 Changes since my first post:
 
 on the first computer:
 1. in the rc.conf ( on your advice )
 dumpdev=3D ...
 dumpdir=3D ...
 2. firewall rules.
 i made some changes in a script (which was a little buggy) who changed
 firewall rules (with ipfw) to prevent brutforce attacks on .htaccess.
 
 on the second one:
 nothing has changed, expect the traffic divided by 2 because of a load
 balancing.
 
 both of them are using same firewall rules (+ some deny for the first
 one).
 
 
 could it be a problem with ipfw ?
