Longer timeouts stopped working

This is very hard to test and describe, however ..

We are using ssh.net (aside of other things) for deploying containers .. such task could take almost hour. In common there are more cascade tasks like this, when some of them fails, whole progress should fail. To be safe, there is 120 minutes command timeout set for every call.

It worked flawlessly, in many cases it properly timeouted after some great internal issue, however, last weeks (let's say since mid of 2017/12), we ran into behaivour where it simply stopped timeouting for this feature. Another calls with shorter timespans (like 5 minutes) timeouts ok.

There wasn't any big changes in code or infrastructure, nor ssh.net update. Using 2016.0 - right now, I've updated to 2016.1 to see if it helps.

So, is there anything I could check or focus on? Is there anyone else experiencing something like this?

Inizia riproducendo il comportamento segnalato con SSH.NET 2016.1: confronta un comando con un timeout di 120 minuti con uno con un timeout di cinque minuti, utilizzando un'attività di lunga durata simile a una distribuzione. Verifica se il timeout più lungo scade in modo affidabile e documenta l'ambiente e i passaggi per la riproduzione se non è così.
