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?

This is happening also on the latest 3.0.
The weird thing is that opensips doesn't send anything to rtpengine.
The first opensips/rtpengine exchange on the initial INVITE works ok,
but the opensips/rtpengine exchange on the 200ok fails (no command is
sent by opensips - confirmed by running ngrep on the loopback
interface).
On the next call, the initial offer works fine, but the answer fails
due to no command issued by opensips.

Hello all,

I'm running opensips 3.1.0-beta (latest version) and experiencing
connectivity issues to the rtpengine daemon running on the same host:
ERROR:rtpengine:send_rtpe_command: can't send command to a RTP proxy
(22:Invalid argument)
ERROR:rtpengine:send_rtpe_command: timeout waiting reply from a RTP proxy
ERROR:rtpengine:send_rtpe_command: proxy <udp:127.0.0.1:2223> does not
respond, disable it
ERROR:rtpengine:rtpe_function_call: no available proxies

After an opensips restart, everything comes to normal.
I was running previously opensips 3.1.0-dev and everything was working fine.

The issue starts showing up after a few days with very little traffic.
Is there anyone experiencing this issue?


Thanks,
Ovidiu
