I am running a single SSRS instance that is Reporting Services 2014 SP1 Enterprise Edition.  I have a report that renders correctly in report manager but when I attempt to export it to any non-text renderer I get an exception "Value does not fall within the expected range".

Looking for troubleshooting ideas; the server hasn't received a patch/reboot in five days, the RDL hasn't been changed in 4 months and this report was working great until yesterday. 

Here's the details from the ReportServerService log:
