System.Net.UnsafeNclNativeMethods.OSSOCK.recv webservice exception

Have a client facing web-service which this morning started throwing a very strange exception.

Thread was being aborted.

Gets through all my methods but then when getting the response is falling over.

Anyone seen this exception 开发者_StackOverflow中文版before? Has me stumped!

Thanks
