SHOW CRASH

00000000

No spinlocks currently owned by CPU 01

This long display reﬂects the output of the SHOW CRASH command within

the analysis of a system failure that occurred on a VAX 8800 multiprocessing

system.

The ﬁrst part of the display includes the following information:

! Identiﬁcation of the system and the version of OpenVMS it was running

at the time of the crash.

" Indication that the failed processor (CPU 00) was not the primary

processor (CPU 01), but requested CPU 01 to take a CPUEXIT bugcheck.

(CPU 01 was, in fact, idle at the time of the crash.)

The next part of the display shows information particular to CPU 00:

# CPU 00 encountered an INVEXCEPTN bugcheck while executing the

NETACP process.

$ Although the next step in the analysis might be to examine the interrupt

stack of CPU 00, the fact that the failure occurred at IPL 8 might indicate

that an I/O driver is involved.

At the end of the example, SDA CPU context remains that of CPU 00; its

current process context is that of the NETACP process.
