When connecting lhc@home the Boinc client logs a error message. The reason is that the server add a http header to the reply and the client doesn't drop it. The same problem occurs on the alpha project.

Boinc messages:
LHC@home - 2005-05-07 07:14:41 - Sending request to scheduler: http://lhcathome-sched1.cern.ch/scheduler/cgi
LHC@home - 2005-05-07 07:14:44 - Scheduler RPC to http://lhcathome-sched1.cern.ch/scheduler/cgi succeeded

This occurs when the Database is overloaded, and instead of generating a nice reply that your boinc client can read, it sends out a SQL server error message.

The Boinc Client doesn't get a nicely formatted message from the server, and reports that it gets an error message.



I'm not the LHC Alex. Just a number cruncher like everyone else here.
