XF 2.1 Troubleshooting Tip

[penturners]

At (seemingly) random times, my site freezes for about a minute, then I get the error message below (in browser). There doesn't seem to be any correlation with Cron jobs or any other time-based activities. About a minute late, everthing returns to normal. No recent changes, normal operation for months prior.

How do I begin to troubleshoot this?

Fatal error: Uncaught XF\Db\Exception: Too many connections in /home/MySite/public_html/src/XF/Db/Mysqli/Adapter.php:165 Stack trace:

Your host limits the number of simultaneous connections.

You will need to contact them and ask them to increase the limit and/or monitor to see what is using all of the available connections.
