So the problem is that the process RAM usage grows and grows to a certain point, where the process freezes? Although the system as a whole has RAM spare. Do you get any kernel messages logged? Such as memory buffer starvation? This bug sounds quite serious so I would expect other people to have experienced it already which makes me think that a) perhaps it is a process resource limit you're hitting and/or b) you're using a specific feature that is provoking the problem, that not many other people are using. I don't know anything about VyOS but if it sits on top of another OS (Linux or BSD) they both have their own process limits and configuration parameters. -Paul-
