I'm using appengine already for a long time, but today, my application is already after 3 hours over quota (> my daily cost). The dashboard howevers show almost no resources have been used, so it should be nowhere near this daily limit.
Also strange is that, dispite the fact that the dashboard says my daily limit is reached, I noticed that I have no problem for retrieving. Only writing to the datastore gives an over quota exception (com.google.apphosting.api.ApiProxy$OverQuotaException: The API call datastore_v3.Put() required more quota than is available). The statistics below however show there where not a lot of writes. If I look to Quota details, all indicators are Okay.
Billing Status: Enabled ( Daily budget: $2.00 ) - Settings Quotas reset every 24 hours. Next reset: 21 hrs
