The first thing is to pinpoint exactly where the crash is happening,
and what is causing it. Try running the agent under a debugger,
and trigger the crash - what does a backtrace show? What does
the code look like at the point where the agent crashed?

See [url]http://www.net-snmp.org/wiki/index.php/Debugger[/url]
for details.
