Admission Webook for closing stream soetime doesn't get called

[Pernifloss]

Hello,
Sometimes the “closing” Admission webhook is not called.

Our client stream using a software developed by my company that stream in RTMP using FFmpeg.

I'm not able to reproduce on my own with either OBS, or our software.
Our clients stream sport event, often Ski and have very unstable connections.

But almost every time one of our client stream the whole day (with lot's stream restart) I have more opening than closing call from OME.

This is problematic because I want to aggregate statistics for a whole streaming session, and I can't do that if I don't know when a stream ends.

Does someone have an explanation on why we don't receive the closing Admission webhook in some case?

We use OME 0.16.3

Are you sure the incoming connection is actually closed?

[Pernifloss]

Hello, What do you mean by that?

Client have only one stream key and have more open admission called than I have close, for the same key (like 7 open for 2 close).
All the streams come from the same computer with the same software ( that stream through FFmpeg ).

This problem can only be solved by reproducing it. Can I use that software to reproduce it?
