Hello,
I've tested again, this time including a single sql_pvquery function in the
event-route. Kamailio will also exit with "daemonize(): Main process exited
before writing to pipe" in this simpler case.
In the documentation, it is stated that: The event route is executed only
once, after core and module initialization, <emphasis>but before Kamailio
forks any child processes</emphasis>.
Does this mean that I don't have (perhaps) access to pseudovariables
during execution of this route? Is this the reason why kamailio exits
prematurely?
Thanks,
George
