I was trying out my patch in another thread and experienced a segfault. It
ended up the segfault is not caused by my code at all. It's not really
bothering me but it's something devs might want to take a look at...
I'm using Nagios 2.5 with the fix for unscheduled triggered downtime entries
from CVS.
So with:
define servicedependency {
hostgroup_name [Some hostgroups]
service_description Service name
dependent_hostgroup_name [Some hostgroups, same as in hostgroup_name]
dependent_servicegroup_name Servicegroup
notification_failure_criteria c,u
}
When I run nagios -v I get a segfault. If I replace
dependent_servicegroup_name with dependent_service_description it works fine.
Backtrace (I changed some recognizable names in it, but did not change length
and kept unique names unique)
(gdb) run -v /etc/nagios/nagios.cfg
