Which flavour of database are you running [MENTION=6886]Bozza[/MENTION]? I'm an SQL dork and happy to answer questions / help out if possible.
These keep happening periodically and I still don't know why.
Typically NSC becomes unavailable for 2-3 minutes at a time and then returns by itself.
To try and help me diagnose what the hell is going on, can you please post to this thread each time it happens, as soon as the site returns, as I want to see if there is any pattern in the times when it takes place, and I'm not always online to experience it myself.
Hopefully I can get this frustrating issue sorted sooner rather than later - sorry it's such a pain.
I don’t know your infrastructure but if your application is not logging error, does the OS event logs indicate problem? e.g. if hosted on Windows server, check Event Log.

It will be a version of MySQL or MariaDB I am sure. My instinct thinks this isnt actually a database error as such more likely a problem Apache or something
Yeah, pretty standard LAMP - Linux, Apache, MySQL and PHP.
vBulletin is very good at logging issues which makes fixing them or, at least, knowing how to fix them, pretty straight forward. This stuff isn't being logged anywhere I can see though, and I've had the hosting company where we have our own dedicated server look too. They don't have specific vBulletin knowledge though.
What I'm a bit confused about is surely you rent the servers from some host, why are their technical team not backing you up?
I think vBulletin won't produce any error logs because it's not an error within vBulletin, it's just reporting that it can't connect to the database. It sounds like it's an issue with your host, rather than vBulletin. Your host should be resolving this for you. This might help: https://www.vbulletin.com/docs/html/cantconnect
VBulletin reports all DB issues including not being able to find the DB.
I’ve been dealing with those issues and logs for the best part of 17 years now and have 220,000 emails from where they e been reported!
