XF 2.3 XF\Db\Exception: Too many connections

[RenegadeMonster]

I have had my forum hosted on AWS for a few years now, and as far as I can tell there are no changes in traffic. Peak traffic is around 100 users (members and guests).

Up until the last week or so I have never gotten this error before and now I have gotten it over 1300 times.

It started to happen around the same time I upgraded to 3.3.6 so I don't know if it could be related or not.

This forum is the only thing on the EC2 and RDS T3.small MariaDB database.

What are some things I should look for that could be triggering the too many connections error.

I'm not sure how AWS operates , ie; singular or shared hosting but if its shared, they could have likely changed some configurations to offset. If its similar to a VPS then I would adjust your my.cnf (maybe use Releem to optimize) and use guest caching to offset live queries on static content.

So far so good this week. I haven't experienced the error since 9:00pm Saturday night.
