I haven't tested but I'm pretty sure, given the experiences of others here, that the actual cause of my NodeBB breakage was dbsearch 0.0.16, so while it's awkward to be told there are all of these upgrades available, I don't think the problem was nbbpm, just a bad plugin.
fuser -k 3000/tcp
seem to fix it so it will kill all to processes using that port
It may do work. But it is not very clean and can lead to serious problems to solve problems of this kind that way.
Just a little advice. No offence.
