Why have I reached the credit limit?

You may have reached your credit limit because of one of the two following reasons:

1. The number of containers in accepted/released/picked up requests with you as the user has surpassed your credit limit

2. Your credit limit has deteriorated and has fallen below the number of containers in accepted/released/picked up requests with you as the user
