WCF webservice seems to be going in an infinite loop - wcf

Question

I have a web service I have created and I am calling a method inside it and logging to a text file. It seems to be re-starting this method for an infinite number of times as it keeps logging the same line. I suspect it could be something in my config file that is wrong, can someone veryfy the bindings etc pls?

Answer 1

The issue here seemed to be: lack of RAM on the server / too many ExecuteQuery requests in the Web Service Code.
