As stated in the MSDN Library:
"Execution engine errors are fatal errors that should never occur. Such
errors occur mainly when the execution engine has been corrupted or data is
missing."
I would suggest you check the Message and the StackTrace properties of the
exception class to see if this provides any hints. Also check your event
log to see if there are any hints as to this error.
Finally try running your web service in IIS to see if the same problem
exists. If not, then you know the problem has something to do with your
"small web-server component".
