This does not happen all the time, in fact about 5% of the time, but here's the error message when trying to "manage subscriptions" for an SSRS report: Unable to read data from the transport connection: An existing connection was forcibly closed by

Troubleshoot issues with Windows SharePoint Services.
Now if I send a copy of the report to file, rename it, upload it again, and try again -- then the error message usually goes away. In short, intermittently the subscription capability goes away for a given report and then only way to get it back
is to delete the report and re-upload it under a slightly different name.
