Solitary Ack error loop when controller abandons BDX log download

Open ksperling-apple opened this issue 1 year ago • 3 comments

I have observed a number of instances where abandonment of a BDX log download by the controller causes the device app to go into a "loop" of attempting to send a solitary ACK. I don't think it reproduces 100% of the time though.

So this is a case where the session is gone for some reason?

This looks a lot like https://github.com/project-chip/connectedhomeip/issues/16805.... but maybe now we have a clearer way to see what's going on there!

Hm yeah maybe it's the same issue. This happened when I stopped the controller side, does that close the session somehow?

I would not expect it to, generally..... At least not given our current code; we do not send CloseSession (though it would be nice if we did).
