[op5-users] So, Merlin & Nagios @ FreeBSD!

[Michael Friedrich]

What tells

bt full

in gdb? Also, you may change the optimization flags to -O0 (0 Zero) to 
see more values.

To really debug the module, you need to know how it's being called from 
nagios (exact path). and then fire up

gdb nagios
run <nagios params with broker module>

Kind regards,
Michael
