Hi,
my customer had a problem about SMP,the following was customer's envirment:
machine:AlphaServer 2100 4/200
memory:256MB
Processors:4 CPUs
When users used dbx to debug a program,the system would be down(I couldnot
determine
whether the phenomenon was associated with using dbx),sometimes very
frequently.
I read the messages produced by the system,and thought there would be some
paremeters unmatch the system.I need your help,it will be appericiate if I
received
the reply.The following was the messages:
EVENT class ERROR EVENT
OS EVENT TYPE 302 PANIC
SEQUENCE NUMBER 1
OPERATING SYSTEM DEC OSF/1
OCCURRED/LOGGED ON Fri Apr 25 12:05:10 1997
SYSTEM ID X00020009 CPU TYPE :DEC 2100
SYSTYPE X00000000
PROCESSOR COUNT 4
PROCESSOR WHO LOGGED X00000002
MESSAGE panic(cpu 2)delete_pv_entry
_mapping not in pv_list
And the 4 CPUs occurred the same error messages.
Thanks & Regards

Which operating system is this on? Several people have reported problems with debuggers on V4.0B, so I've been checking that one first. That started showing up at V4.0B when the kernel is built with the KDEBUG option. Not all machines experience the problem, and I'm not sure if the 2100 is one that does. If the above applies, rebuild without KDEBUG, and the problem should clear up. But then again, it may be something else entirely. Start with the OS version and see if there is a crash_data file produced in /var/adm/crash. Otherwise the information you have given us is a bit small to start with. PeterT | |||||
