Server crash
I have a server with HP-UX 11.00/800 (L2000). This machine halted twice and the most different syslog message is:
syslog: System error initializing semaphore, Device busy
When this problem occur, my server not respond ping, telnet and console login. Can anyone help me? Is there any patch to solve this problem?
Thanks,
Jansen.

Re: Server crash
system hang totally - you have to reset it?I'd
wait for such an occasion and perform TOC (Transfer Of Control) from the GSP (Ctl+B) card.Hopefully,saving crash is enabled and you
can extract the stack trace from the crash later (or pass crashdump to HP support center for analysis).It also can be due to process holding a device or high context switch content conditions (many processes are fighting for a specific device like io etc).
I'd go for producing a crash and checking it.
best regards,
Zeev

Re: Server crash
It will be a subdirectory.
You can perform q4 dump analysis on it and figure out what the error is. Then you can search itrc or contact hp with the analysis to figure out what patch you are missing.
Attaching the instructions.

Re: Server crash
when this problem occurs I have to reset the server using GSP. The server don't crashed with a red light on the front LCD panel. Thus, I don't have crash dump files in /var/adm/crash.

Re: Server crash
