SOAP returning values is flakey

Hi, I have a SOAP server running and a client connecting to it. I'm getting worried as during development I have noticed that the chance of getting the return value from a SOAP method seems random. Some times it will return fine, other times nothing comes back - doing a var_dump of the return value from the $soapclient->call() it simply displays: object(soap_fault)(7) { ["error_message_prefix"]=> string(0) "" ["mode"]=> int(1) ["level"]=> int(1024) ["code"]=> string(4) "HTTP" ["message"]=> string(0) "" ["userinfo"]=> string(0) "" ["callback"]=> NULL } Which is not very helpful! Sometimes when I've refreshed the pages a lot I've received a "Invalid HTTP Response" too :-/ Is this a bug or an obvious mistake I've made in using the SOAP implementation? I really hope somebody can help me out of this problem :-) Thanks in advance, -- Mike Carter [web developer] tel: 01925 758229 // fax: 01925 758023 // web: www.koa.uk.com This message is confidential.
