Problem with dumpon...

[Ivan Khilko]

Hallo.

     I have server (Pentium III) with FreeBSD-5.5 on it.  On this server I
configure gmirror RAID 1 on IDE HDD:

kernel: ad0: 76319MB <ST3802110A/3.AAD> [155061/16/63] at ata0-master UDMA66
kernel: ad2: 76319MB <ST3802110A/3.AAD> [155061/16/63] at ata1-master UDMA66

All work correct, but sometimes server rebooting. Background file system checks
off on this server. I can't find cause of this rebooting. Server work on
unattended room. When I come to this room I see only: "Automatic file system
check failed...". When I configured crashdump, kernel say:
  dumpon: ioctl(DIOCSKERNELDUMP): Operation not supported
(swap device on /dev/mirror/gm0s1b)
Logfile (syslogd: *.* /var/log/messages) not have any error messages.

How I may determinate cause of problem?



Ivan.
