Hi All

I am working with old system 7026 - B80, the system was restarted
abnormally. We were not aware while the system was reboot as it was in
midnight. I need to know the cause for this reboot.

I have checked the following things...

1.Checked error with errpt command, unfortunately error logs gets
clears at frequent interval, I could not get the error for that period.
So, this option is ruled out.

2.No peak process was there during the time.

3.Disk space issue was not there.

4.cheked /var/adm/messages, but, nothing got logged with. In my
syslogd.conf, all were asked to log into /var/adm/messages.

5.checked with "last" command, it shows reboot @hh:mm, no other
information like "whose login and ip address", so, it was not reboot by
anybody and maybe through other actions.

6.Checked is there any dumps, no dump is created for that time.
  sysdumpdev -L shows, dump of year back.

plz help me in this case...

thanks in advance...
