[OpenSIPS-Users] rtpengine_delete not returning immediately

[Alain Bieuzent]

Hey John,

I just take a trace with timestamp to see what is the delay in our side (rtpengine with around 2000 calls engaged)

Sor for me the "ACK" of the delete come less than 1 ms after so no issue
I'm using Version: 7.5.5.1+0~mr7.5.5.1 on Debian 9

    Johan,

    I did not want to raise an issue on github before I was sure that I wasn't
    doing something stupid.
    I have the impression that there are many people using rtpengine, some of
    them for high capacity applications.
    If there really is a blocking delay of about 3 seconds on every call to
    delete, then you would expect to see some really bad things happening under
    heavy load.
