Long and intensive reports, as well as short timeouts in various parts of the configuration can cause conflicts when running reports. Dues to this you may experience one of the two following errors:
Error calling webservice. Details: 'timeout'
or
Error calling webservice. Details: 'Unexpected server error occurred whilst performing this action. Further information is available in the server logs'.
When viewing the application overview, the following message is displayed:
ActiveNavigation.Core.Logging.ErrorEntry: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Resolution
The following two values are in SystemSetting table of the Discovery Center Database Systems. Update these rows using SSMS, then restart the scheduler service and IIS to adjust the timeouts.
('DB_TIMEOUT', '600', 'Database Timeout.', '', null, 4, 3);
('LONG_OPERATION_DB_TIMEOUT_SECONDS', '50400', 'Long running Database operation Timeout.', '', null, 4, 3);
