When I load the developer console, I get a "Total Requests Limit Exceeded" error. This is on a dev org. I have been using the Force.com IDE all day, and have been writing alot of unit tests (and running alot of unit tests). What is going on here? Am I just working too hard :P
It sounds like you've ran into your API Limit for the 24-period.
Check this. Go to Setup and then click
You API Usage will be on the top right. If you are at your maximum, I suggest calling Salesforce-Support immediately, and ask to get your API Limits increased temporarily. SF-Support is generally friendly and will usually grant the request. (If you have 5,000 API calls/day, ask for an increase to 10,000 temporarily).
