How to get no buffer accumulation on the server side?

Hello guys, how are you?

I'm trying to deploy a low latency stream.

Once I start the stream from the FMLE encoder, I get very low latency on the client side, but if there is any internet connection instability, and auto adjust performs, the result is:

First a break stream on the client side (that's normal), but after the video is back I see a accumulation of delay, or buffer, like if the server was retaining buffer. Is there a way to always keep the buffer to a certain value of seconds? so my stream has always a low latency, no matter what?

Here is my setup:

Encoder side:

Enconding from FMLE

1280x720 60p h.264

Keyframe interval 1sec

autoadjust enabled

Server side:

Adobe FMS 5.0

Client side:

jwplayer

bufferlenght set to 0.1

Thank you in advance
