[Mono-devel-list] Problems with Webservice client

[Jörg Rosenkranz]

Hello,

We're having problems accessing a webservice written in PHP. When we're
doing many requests to this web service we're getting a number of 
different exceptions:

1)
WebException:	The request timed out
Status:		Timeout    	
Stack Trace: 
    in <0x001b6> System.Net.HttpWebRequest:EndGetResponse (System.IAsyncResult)
    in <0x00092> System.Net.HttpWebRequest:GetResponse ()

    ...    
		
2)

    ...
    
3)

Status:		RequestCanceled

    in <0x0021c> System.Web.Services.Protocols.SoapHttpClientProtocol:Invoke (string,object[])
    ...    


Our problem is: It's not possible to reproduce this behaviour in a 
simple test case.

Are there any ideas how to track this down? It would already be very 
helpfull to exclude one of the involved components (PHP web service,
Apache, Mono web service client). Are there any tracing facilities?

Any help is highly appreciated because this is a major problem for us.

Thanks,
Joerg.
