From: Josh Billingsley on
I have a pair of SSRS 2008 servers that the SSRS Service fails
intermittently, typically once or twice a day. The report server database
is on a separate SQL Server 2005 machine.

In the Event Log, the following error message appears when the service
fails:

Report Server Windows Service (MSSQLSERVER) cannot connect to the report
server database.

In the Report Server Service log, the following messages appear:
rpcserver!DefaultDomain!6fc!10/08/2009-19:38:03:: i INFO: Managed server
timed out possibly caused by slow GC. Granting additional timeout of 30 sec.
rpcserver!DefaultDomain!6fc!10/08/2009-19:38:39:: e ERROR: Managed server
timed out. Timeout=150 sec. Gc extension timeout=30 sec.
rpcserver!DefaultDomain!6fc!10/08/2009-19:38:39:: i INFO: Generating a dump
from the RPCServer ProcessMonitor.

None of the other applications that share this database server loose
connection to the database server. What could cause this?
