HP-UX System is automaticly crashed down

[Soeguet]

Hello together,
I've a HP-Server 9000/859 with OS HP-UX B.10.01. The system crashed automaticly down very often. I've looked in the Log-Files /var/adm/syslog.log. But I dont't see anything in this logs abount the reason of the crashes. Where can I still look ?

Bye

You should have data in /var/adm/crash, subdirectories and all.

If not, you should check the settings in /etc/rc.config.d/savecrash

The first variable should be set to 1. If you have to change it, do so, restart your system and wait for the next crash. Then you will get data.

In addition, make sure that /var/adm/crash has enough space to capture the core images.

Check for a panic string in /etc/shutdownlog.

Well, this is my second attempt to attach the 'q4' document. In it refer to 10.00 procedures like 'savecore'.

If you don't have HW support then attach the files indicated, like:

/etc/shutdownlog
/var/tombstones/ts99, etc.

Hello,

how many space must have the system in/var/adm/ to save the crashes images ?

Hi,
if your previous startup ended with a crach, then look at the last line(s) of OLDsyslog.log, e.g.:

# tail /var/adm/syslog/OLDsyslog.log
which may give a clue to what brought the system down.

regards,
John K.

Refer to section 1.4 in the q4 attachement:

# savecore -vr

I've attached it again.

diagonise your crash files for the panic on the system.

Just checked the patch database and found this patch for Conditional trap as for in your case.

Have it installed

Please continue the 'q4' analysis. Here's the most I could find on 'Conditional Trap' and its very ambiguous:

"...The Instruction Address Offset Queue (program counter) is not advanced when a trap occurs on Series
800 systems. If a signal generated by a hardware trap is masked or has its signal action set to SIG_IGN,
the program loops infinitely since the instruction causing the trap is re-executed, causing the trap again..."
