We are currently experiencing problems with our production OpenSER (1.1.0) environment where the load on the server is steadily increasing and the OpenSER response time increases drastically (e.g., 30+ seconds for an internal call to ring).
this might be because of some slow DNS or database response. The best is to run in higher debug mode to see where it gets stuck. Another possiblity is the syslog, make sure it is configured to be asynchronous. If you have lot of messages written to syslog synchronous, then you will get lot of delays.
Daniel,
Thank you for this info. It appears switching to asynchronous syslog'ing was a huge win for us.
To troubleshoot, see which application eats most of the CPU, if that happens.
On the other hand, with 1.2.x you get better performances and parsing error handling via error_route. You should consider upgrading.
We are investigating 1.2.1. Better performance always sounds good.
Thx, David Coulthart
