message contains an invalid or expired security context token

Hi Folks,

I develop one wcf service application with wshttpbinding. I got an error message like below, when my system is idle more than 10 min.

{"The message could not be processed. This is most likely because the action
'http://tempuri.org/IDataSchemaService/GetBySearch' is incorrect or
because the message contains an invalid or expired security context token or
because there is a mismatch between bindings.
The security context token would be invalid if the service aborted the channel due to
inactivity. To prevent the service from aborting idle sessions prematurely increase
the Receive timeout on the service endpoint's binding."}
