[OpenSER-Users] OpenSER - a slow starter?

[Klaus Darilion]

MAybe openser tries t do some DNS lookups which may take long time.

The best would be to set debug=4 and "tail" to the logfile 
(default=/var/log/syslog (or /var/log/messages on RedHat&co)).

Then start openser and watch the logfile.....
