Starting our main application with subagent causes coredump.

[Need H. <snm...@ya...>]

I was successful in getting the subagent to start upon booting up our hardware box.   Once the box comes up, I can then telnet to it and start the snmpd master agent successfully and then I could see the subagent attach itself to the master agent eventually.   I then can run SNMP requests and everything works great.  

** Note: The master agent is started manually once the box comes up for testing only (until we integrate that into our load build process).

Normally our hardware box would start up our "main application" upon reboot first, however, for testing purposes I was told to simply start the subagent SNMP application only.   Anyway, since I had the subagent and master agent stuff working perfectly, I decided to put back in the logic to start our "main application" first and then follow this with starting up the subagent application.

When I reboot the box, I can see the "main application" is requested to start and then I see the subagent is requested to start.  At this early booting stage, I can even telnet into our box and start up the master agent and perform a subagent-specific query to verify it works fine.

Then after about 20 to 30 seconds into our boot process, I get a segmentation core dump.  It seems something to do with the subagent is timing out perhaps ... dont know.   Does anyone have any ideas on what could be causing this?  

Again, if I reboot the box and start only the subagent application OR only the "main application" then each application works fine, however, when they both try to start up during reboot processing, then I always get a coredump.
