Question HELP: A01app segmentataion fault when /run/beamOn 3 

Keywords: segmentation fault
Forum: Documentation and Examples
Date: 10 May, 2005
From: Tim <timtran@jlab.org>

Hi,

Thank you for reading this request-for-help message.
*********************************
Linux System: Red Hat 3.4.3-9.EL4
geant4.7.0.p01 with CLHEP1.8.1.0
*********************************

A01app appears to run fine for "/run/beamOn 1" or "/run/beamOn 2"  
However for "/run/beamOn 3 and onwards", segmentation fault occurs.
Most of time, no screen output is given when fault occurs, just "segmentation fault".  
Occasionaly, there was some screen output, as listed below.

I will tried to see if I can provide crash report with debug info. 
Since I am new to geant4, this may take sometime.
So I post the message to see if some one can provide a solution before 
I can produce the debug crash report.  I will work on it.
Let me know what additional info you need to diagnose the problem.
Thank in Advance.

By the way, I am not sure if the outputs are correct from the runs "/run/beamOn 1" or "/run/beamOn 2".
Are their output example that I can check against?

Tim

Here is a list of output when I tried "/run/beanOn 3"
