This is all I get, Rick...

Ok, refresh that from time to time. That looks good. It means at the time you ran that, there was only 1 active connection to the database.

Keep refreshing it, especially if the error pops up quite a bit, when it does pop, if it truly is a connection number problem, then you should see a long list of connections.

SHOW VARIABLES <-- run that sql and it will show the variables

there are 2 fields

max_user_connections (usually 0 -- unlimited) and
max_connections (default 100)

Linky Poo™

for more info

ah yeah, forgot about that

Yeah, run that and then look for the max_user_connections to see what they have it set to.

25 seems kinda small?!

As for show processlist, I keep getting just the one line

25 is pretty small, especially if there is any sort of delay in any of the queries running. If any happen to need to do some sort of table lock while the mysql server is a bit slow then anyone else on the forums at that point will get queued up.

So, 25 connections could conceivably be taken up in very short order. Normally, even on this site, I'll only see 1-3 active connections. But there are times it can spike up for sure.

That being said, the error you are getting normally seems a bit odd. "Couldn't connect" is pretty generic, definitely not coming from UBB.threads, and the fact that I can get this error on your site when show processlist is showing only 1 active mysql connection is pretty suspicious.

For anyone following along, this isn't threads related. It's a custom island issue with trying to connect to a database that apparently doesn't have permission

It is? I know Who's Online stopped working... OH! So did the TV Listings... hmm... You're right! That's where the error message is coming from. I'll have to look into why it just stopped working all of a sudden. I know they moved the server it was hosted on - maybe it has something to do with that. I'll disable it and see if everything else starts working again...

Check your PM, you posted right after I posted to you

A public thank you for tracking that down!!

Rick Rawks!
