system always hangs when using the same C binary

[Guettache]

Hi,
Refering to a my previous message posted the 5/07/2, I found out that a C binary was causing my system to hang (needs then a hard boot to get it back running)

This is the info from the crash dump and note from HP:
==============================
What I see in this dump it is a HPMC, but it looks like a arpa or btlan
problem on your network card:

I have updated all the network patches, but it did not solve the problem.
We have changed the network card, but still the same problem.
I found out later taht the system hang always happed when an in house application was being used.
I have to tell you that we just have upgraded from a D210 system running 10.20 (32 bit processor) to
an L1000 running 11.0 (64 bit processor)
The application has always worked on the old system and ported to the new one without any problem.

The day before the crash started, I recompiled the application (in house developped) on the new
system (using ansi c compiler :
LINT B.11.11.04 CXREF B.11.11.04
HP92453-01 B.11.11.04 HP C Compiler
$ Sep 8 2000 23:13:51 $)

Question: Why the new binary recompiled with the new system has caused the server hang when using it.
This application is used in user mode. I monitored with TOP command the running application It was the highest process.
%CPU reached 24 and then the system hanged.
Hope some can help

Hi

1)get the crash dump properly analysed.


2)make a tusc wrapper for the application and trace it.

Hi Steve,

I have downloaded tusc.
I have no manual page for it.
Could you may be tell me how to use it?

Thanks a lot
