Hi,
I added nine subscriptions to the SSRS manager in order to generate 9 Reports based on CRM data. These reports will be trigggered every monday night by using an interval of 10 minutes. E.g. 1.00 am, 1.10 am, 1.20 am etc.
Previous monday all reports have been generated. This monday only eight reports have been generated. One failed. The failed report was started at 1.40 am. An exception was written to the log at 1.47 pm:
library!WindowsService_8!c68!04/18/2016-01:47:33:: e ERROR: Throwing 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.; dbcleanup!WindowsService_8!c68!04/18/2016-01:47:33:: e ERROR: Error in CleanOrphanedSnapshots: 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. ---> System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
This is the complete log:

library!WindowsService_8!c68!04/18/2016-01:47:33:: i INFO: Call to CleanBatch() endsIf I trigger the reports manually in a row, no problems occur.
Does anybody know the reason for this issue? I checked thet imeout settings of the report server, they seemed to be ok. Is it possible that the subscriptions "steal" resources from each other? The exceptions are not very meaningful.
Best regards
