SNMP_CLASS_TL_FAILED error

[Kevin J. Schmidt]

I have a simple trap receiver that is based on the receive_trap.cpp that
comes with SNMP++. I've noticed that the application SEG faults every so
often. If I do a "where" in a gdb session, I see the following:


Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1024 (LWP 15229)]
0x08056bb6 in callback () at eval.c:41

#4  0x0806cded in SNMPProcessPendingEvents () at eventlist.cpp:249


What caught my eye was is the stats=-22 at #1. According to snmperrs.h,
-22 is SNMP_CLASS_TL_FAILED. My first question is whether or not this is
the same error that the CNotifyEvent::Callback method is seeing, and if
so what is causing it? Also, does anyone know if this is what could
cause the SEG faults I'm seeing?

Thanks,
