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

[Ovidiu Sas]

Hello Razvan,

The system is a debian buster one.
I patched the code:
#ifdef IOV_MAX
    LM_NOTICE("IOV_MAX=[%d]\n", IOV_MAX);
#else
    LM_NOTICE("no IOV_MAX\n");
#endif

and I get:
NOTICE:rtpengine:send_rtpe_command: no IOV_MAX
in the logs.

Then I patched the code again to check how many buffers are being used:
The max so far was 73:
LM_NOTICE("writev(rtpe_socks[node->idx], v , %d)\n", vcnt + 1);
got me:
NOTICE:rtpengine:send_rtpe_command: writev(rtpe_socks[node->idx], v , 73)

I will continue to monitor the system to see if there is a correlation
between the error and the number of buffers.

Thanks,
Ovidiu
