HELP! - The Report Server Is Not Responding

Hi,

RS 2005 (sql 2005 SP1) on Windows 2003 SP1

The report server was running ok until this morning. Its just giving a "The report server is not responding. Verify that the report server is running and can be accessed from this computer." message when trying to open the report manager.

Any ideas?

In the SQLDUMPER_ERRORLog.log file there is this..
