Unexpected WSE 2.0 errors in Event Log

[Robbert van Geldrop]

Hello,

We run a very stable and well functioning ASP.Net 1.1 webservice using WSE
2.0 sp 3.

Every now and then the following error appears in the system event log:

HTTP/ASMX Message Receive Failure: System.Xml.XmlException: This is an
unexpected token. The expected token is 'EndElement'. Line 1, position 4387.
at System.Xml.XmlTextReader.Read()
at Microsoft.Web.Services2.Xml.XmlSkipDTDReader.Read( )
at System.Xml.XmlLoader.LoadCurrentNode()
at System.Xml.XmlLoader.LoadDocSequence(XmlDocument parentDoc)
at System.Xml.XmlLoader.Load(XmlDocument doc, XmlReader reader, Boolean
preserveWhitespace)

Microsoft.Web.Services2.Messaging.SoapPlainFormatt er.Microsoft.Web.Services2.Messaging.ISoapFormatte r.Deserialize(Stream stream)
at
Microsoft.Web.Services2.WebServicesExtension.Befor eDeserializeServer(SoapServerMessage message)
What can I do about this?

Hello,

It seems it receive the incorrect soap message which is not well formatted.
Unfortunately, we cannot tell more details with current information. You
may need to catch the exception in code and check what message/object cause
such a problem, and test if the problem is reproduable.

Hello Luke,

Debugging this will be hard, since so far we did not see an exception
attached to this logging behaviour, since it is not our own application that
logs this but WSE.

Is it possible to stop WSE from logging this error to the event log?

Regards,

WSE only will raise an exception to your web service. The Eventlog part
should be in your web service. You may check if your web service project
have any exception handling part and try block the exception there.

Hello Luke,

We have some more progression on this issue. The problem is caused by the
WebProxy on a client, that is not threadsafe. If the proxy is accessed by two
threads for signing and sending a SOAP Request the WSE interface has trouble
decoding the SOAP:XML on the server side. The WSE dll logs an entry to the
EventLog in that case. The SOAP-request never resolves and this means we were
unable to debug it, since nothing happened in our code.

It means that WSE 2.0 dll logs errors to the EventLog by itself. We do not
log anything at all.

I expect that you look into this to see if the logging of these errors to
the EventLog can be disabled (or redirected to a different log group). Can
you please look to this?

Kind regards,

Hello,

After searching more documents, I found a event og source "Microsoft WSE
2.0" will be created when WSE 2.0 is installed on a server. But I didn't
finda way to disable it. The only way I think is not to grant the
application the permission to write event log.
