rtp_receiver_threads parameter problem

[pumper]

Hi I compiled sems with instructions of wiki on debian 11 and installed it successfully. it runs and works normally .
I have a virtual machine with 32 core cpu and 32GB of ram and try to use sems for more than 5000 concurrent calls with 1500 cps so i tried to set rtp_receiver_threads=8 and restart sems. it seems everything works but i get alot of errors in sems log like thease:

please help me with this strange problem

@pumper Yes, I also encountered this error and as I noticed it correlated with sems crashes.
I ended up eliminating the RTP handling (left only SIP).
If you've determined the cause, share please the information.

I have looked into this and I can confirm that this issue exists when sockets get reused faster than the stream cleanup completes. Im unsure Im able to fix this anytime soon. If you have any more infomation you can provide please do so.
