How many agents do you have checking in?
Are you collecting event logs and emailing these to a support account. I've seen a similar problem when all alerts were being forwarded to a monitoring email account.
If you go to System - Outbound Email choose the Log tab and see how many emails have been sent on a particular day.
You might also want to go to System > Statistics and click the semi-hidden link Statistics Collected which will show you various graphs of how well your system is performing, you do need to know a little of what these mean but most are self explanatory.
Reviewing what info you have given it looks like you either didn't scale your server correctly (not enough resources, or you did it in a virtual with not enough resources), or you are collecting too much data (D drive using 200 GB of data). I recommend that you immediately submit a support ticket and ask them to review your server so they can correctly advise you on what you need to do to fix this.
