MS Dynamics CRM 2011 throws intermittent [CryptographicException: Unknown error "-1073741823".] when invoking REST API from BizTalk - dynamics-crm-2011

Question

I'm calling the CRM REST API for changes in AuditSet via WCFWebHttp from two different BizTalk applications. Everything is configured identically for both applications
One application works fine without any exceptions, but the "new" one fails intermittently with the following exception:

I've used Fiddler to monitor the calls and there are no differences between calls which are successful and those which fails
