I would check your EPiServer scheduler configuration. It looks like it can't remote to the EPiServer instance when trying to run scheduled jobs so is throwing the exception.

Try stopping the scheduler service first to see if that stops the logs getting entered and work from there.

Ps the file you want to examine is C:\Program Files\EPiServer\Shared\Services\Scheduler Service\EPiServer.SchedulerService.Sites.xml

I think the logging feature for the Scheduler also works for CMS 6. See:

http://www.epinova.no/blog/Tore-Gjerdrum/dates/2010/11/enable-debugging-in-episerver-scheduler/

It might give you some more information about the problem.

Below is the log from the scheduler (on the internal test environment)

I have also included the WCF-configuration in web.config.

And episerver-log is still being filled up...

What we ended up doing was to hide the warning instead of fixing it.  We added the following to EpiServerLog.config:

	<logger name="Microsoft.Samples.Runtime.Remoting.Channels.Pipe.DBG" additivity="false">
		<level value="Error" />
	</logger>

Problem solved :)
