[OpenSIPS-Users] rtpengine errors: can't send command to a RTP proxy (22:Invalid argument)

[Răzvan Crainea]

Hi, Ovidiu!

I doubt this is a problem of OpenSIPS version, but rather of the OS you 
are running on. I suspect that error comes from the fact that the bson 
resulted has more than IOV_MAX elements, which if I recall correctly it 
was 15 on some OSes.
We had a similar problem in rtpproy[1], where we had merged the buffers 
in a single one just to pass over this limitation. Could you check if 
you are facing a similar issue?
