Server timeout seems to disregard MinimumTimeout

Hi,
I'm trying to understand why my server takes so long to timeout a peer. From the limited information available on the server timeout logic, my understanding is that timeout is determined based on the peer latency statistics, but my server seems to resend ACKs until it reaches MaxTimeout regardless of the peer RTT\VAR. to demonstrate, I've set the maxTimeout to 60 seconds and MinTimeout to 5 - this is how the timeout log looks like:

Can anyone offer any explanation for this weird behaviour? Any parameter which I can configure to fix it?
