I'm looking for either help on an issue or to see if somebody can point me in the right direction to troubleshoot the issue below.

We have reports running in SSRS 2008 R2 SP1 (10.50.2500.0) where a subscription on a shared schedule will sometimes show as hung up in a "pending" state. From looking through the execution log table I found that an execution log record that is normally written wasn't. I have attached a screenshot highlighting the record that was missing a duplicate that day as well as a 0 byte count. I also looked through the SSRS log files (Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles) and they look identical to previous days when I search by report name as well as the SubscriptionID for the scheduled run time. When I rescheduled the subscription to run it executed without a problem. I would like to see if anyone has any advanced troubleshooting techniques that I can employ prior to calling in a ticket with Microsoft. My client is really coming down on me to come up with an explanation for these random report failures and at this point all I can say is "I don't know".

Any help, suggestions or comments are appreciated.

Thanks

Do you have any other processes running on the database at the time of Subscription? For example, back of the Report server Database. It might explain the occasional failure.

I looked into that and didn't see any conflicting processes at the report run time. I did do some other research and found that it may be failing looking up the user SID in Active Directory at run time. Also, the report owner owns most of the reports on the server and I found a setting in the RSConfig (Maximum Simultaneous Report Jobs) that limits concurrent report executions to 20 which might be a cause as well. I'm going to increase the config value to 40 and see if that helps.

Run This code on your report server database and it will give you an schedule to see if you are running multiple reports at the same time

SELECT *  FROM [ReportServer].[dbo].[Subscriptions] order by LastRunTime
