Occasional SOAP errors when making web service calls from C#
We have a C# application making web service calls to RFCs (non-NCO, SAP 4.7, WAS 6.40) and occasionally getting the following error:
The 'SOAP-ENV:Envelope' start tag on line '1' does not match the end tag of 'SOAP-ENV:Envel'. Line 1, position 34560.
This error happens randomly and can occur, not occur, and occur again for the exact same call (same data, same web service call). I anticipate that we might have a missing configuration on one of our application servers, but don't know where to tell BASIS to look. Any ideas or other help would be appreciated.
