OpenVMS crash

Hi all,

I have never seen OpenVMS crash up to now when I run some multithreaded tasks using OmniORB 4.1.3 and SqLite 3.5.7 on fully patched (Update 1000) OpenVMS IA64 8.3.

Application runs fine several hours or even day when system crash.

In SYS$ERRORLOG:CLUE$*.LIS is all the times:

Bugcheck Type: XQPERR, Error detected by file system XQP

Failing Instruction:
UNHOOK_BFRL_C+00550: break.m 100002

I had found minimum privileges to be able to run it (NETMBX , PRMMBX, OPER, READALL) but system crash the same way.

SqLite DB file is exposed over SAMBA V1.1-1 share but system crash when nobody read it.

Can somebody tell me how to interpret such CLUE?

Re: OpenVMS crash

Hi Stehlik,

In the clue crash output, I see these lines:

R8 = 00000000.00002124 %SYSTEM-F-IVLOCKID, invalid lock ID
.
.
R19 = FFFFFFFF.8077DC60 SYS$DEQ_C+00060

I wonder if some lock was being dequeued at the time of system crash and if the lockid was invalid as indicated by the status above.

It appears to me that this problem requires a detailed analysis of the system crash to find the actual cause. You may want to log a call with HP support so that they can analyse the dump file.

Regards,
Shilpa

Stehlik,

Concur. Call support, and be prepared to send them the dump file.

Hi all,

OK I will try to contact HP support.

Just one question - can unprivileged task cause system crash?

>can unprivileged task cause system crash?

Ideally, no. But they can cause conditions that cause a buggy kernel to crash.

Re: OpenVMS crash

Hi Stehlik,

As you say you are running CIFS on this system, just curious to know if there were any SMBD process crash on this system in the recent past. Could you please check if there are any dump files in the directory samba$root:[var.cores...]? Also, could you please check if there is any ACCVIO trace-back information in the log files, samba$root:[var]samba$root:[var]SAMBA$SMBD_STARTUP.LOG;*?

Thanks,
Shilpa
