WCF Service Errors

ERROR 1:TimeoutException

The request channel timed out while waiting for a reply after 00:00:59.9970000. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

SOLUTION:
1)A call to clientservice.close() will solve the problem.
