[SR-Users] UDP workers block when one or more rtpengine instances go offline

Hi Sebastian,

You may need the following fix for your rtpengine module in Kamailio.


We had the similar issue with rtpengine module in Kamailio as it is using package memory and not shared memory. 

Many Thanks

Muhammad Zaka

I actually don't know how long it blocks for one request. But I know that whenever one RTPengine is gone, we get "SIP offline"
notifications from our monitoring system (sending SIP OPTIONS) within minutes. I think, waiting for an RTPengine answer for a second is okay if it happens once every 120 seconds, but it's not okay if it happens every time.
