What your're suggesting here is having queues in kamailio instead of having
them in syslog. You're trying to fix a syslog problem from kamailio side.

If syslog block because it's mesg buffer is full, kamailio will do what syslog
should do. This solution only works for kamailio, and you're in risk of getting
a frozen system anyways, no warranty of having a working kamailio.

Example: You have a cronjob every 5 minutes. This cronjob cannot finish because
of the unresponsive syslog. You'll get a new cron process every 5 minutes until
you no more processes can be called.

Ok. This is a different point of view. That "efficience" word should now
trigger an "Andrei respawn" :)
