Hi,

We are having a query on SIGNAL ABORTS on HP-UX 10.20.
The detailed description is given below,

We are using one product called ReX.
This product is used for Printed Circuit Board Analysis/Repair.

Generally a board is scanned for its identification number thru a
scanner and then details of the board is loaded and analyzed/repaired
using ReX product. There can be many users (around 100) running
the ReX product at the same time.
Many times, users are getting logged out from ReX because of
SIGNAL ABORT (SIGNAL 6,10,11).
This SIGNAL ABORT error occurs maximum during the board scan and
ReX dumps 'core' file.

This SIGNAL ABORT is very random.

Can you please give us some suggestions for approaching this problem?

All I can suggest is general troubleshooting tips to pin down the problem:

Has this problem just started recently? Did it start after an OS upgrade/
 installation of patches/changes to the application/Y2K? Does it happen
 with one user or scanner in particular? Does it just abort that user, or
 do other users get killed off at the same time?

 What do the software suppliers have to say? Have you/they/HP tried to
 analyse the core dumps? From what I can see from "man abort"  SIGABRT
 would typically be generated from an application, so have they looked at
 the code to see where & under what circumstances an abort would be done?

IMO this is unlikely to be a problem with Unix or the hardware; You could
 post a link to this question from the Unix Programming topic area, to see
 if they have any insights.
