I've gotten maybe 10 of these from an integration we have that simply pulls Contract records from production.  Iv'e had these one and off (maybe like 1 every 10 days) for a couple months, but this morning I've gotten just a landslide.    Using reflector, the endpoint I'm pointing to currently (in the app config) is: "https://www.salesforce.com/services/Soap/u/16.0".  

Is there something change that I missed or something like that with Salesforce connectivity?  Thanks.

Any ideas would be most welcome.  Thanks.
