As I wrote a few weeks ago the system run fine with AMANDA and the

changer the automatic backup started and the complete system crashed!!
Solaris didn't give any messages in /var/adm/messages ...
The system was frozen, the only way to get the system back to life was a
"poweroff". After that the system was really fine for a few weeks.
Last week the same shit happend. The complete system was frozen.
The trick is to find out what is happening short before the crash.
I guess amanda just happens to stress the machine enough to tickle
the problem. Amanda uses IO (network, disk, tape), CPU and RAM and
loads the bus (anything else in a computer?).
Run under /bin/script (*) a loop which gathers all interesting
information, like "ps -efl", "netstat -ni", vmstat, iostat, df, maybe
even "dmesg|tail", all intermingled with "date" to get some timestamps,
and hope the resulting file contains some hints of what is happening
just before the crash.
Maybe the console contains a useful error message, which may not have
made it into /var/adm/messages. Make sure it does not go into
powersafe mode or looses the info on the screen by rebooting.
E.g. connect a serial line to a PC with a terminal emulation (Hyperterm
on Windows, or Kermit on Linux) having a very large screen history
buffer.
Also some hardware testing utilities would be nice.
We opened a call but without any messages sun was not able to solve the
problem. During the last two days the system crashed two times.
But now the system does a automatic reboot.
Nice he, payed support :-)
