We are facing one issue related to SSRS. Appreciate any pointers in identifying the real cause of this issue. Symptoms as below. • Our application is a windows smart client with WCF based App server. Report Viewer control is used for rendering reports.
Server side reports are used. • It happens for only for few reports when accessed from client through report viewer control. It is not happening all the time and the symptom is random • The error message is as below Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerStorageException:
An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database., ; chunks!ReportServer_0-6!3e48!07/08/2011-10:59:23:: w WARN: Rolling back shared chunk transaction for snapshot
