Error Message

Solution 1:

Install monitoring then repeat as necessary

• Gather data
• Analyse data
• Make changes based on analysis
• Monitor effect of changes

This isn't rocket science but there's no reason why you can't use Scientific Method.

Solution 2:

You need to look at the code given out in the error message and think if it could exhaust server resources in some way and then either fix the code or postpone problems by adding resources to the server.
