@ganymede Generally we are one version behind. In fact I should probably update to the newest version soon.
The first issue with nodeBB is sometimes the updater doesn't work and I spend hours fiddling with it until the forum comes back up. And the concern is always that if I can't then I might need to downgrade or set up the whole thing from scratch, resulting in downtime.
The real issue though is there's a memory leak... somewhere. Although the specs for the VM I got MSB running on are pretty generous, this thing eats memory. Eventually it craps out and I need to manually restart it.
The ideal solution is that someone with more time than I do wants to take over the task of supporting MSN on a technical level. I'd then pass over the credentials and they can take care of it going forward. But such a person hasn't stepped up.
Another solution is to get more hardware. It'd cost more though (double) which at some point will be a burden on me. It'd also not remove the leak issue, just mask or make it happen more irregularly.
A third approach would be to migrate to a different platform. However there are definite downsides to that, too; for starters it might have other, new, exciting problems of its own.
The other is that we'd almost certainly lose all the existing post going back years, and that's definitely not ideal, unless there's a migration script that will work.
As a side note I do take nightly rotating backups of the whole site so there's never a time we don't have 14 days' of rollback. Those are kept both on-site and on a separate host I run at home. But even this mitigates, it doesn't remove risk.
The short of it is... if someone wants to support MSB technically I'd love it.
