Server Losing Results?

How do you know you have already crunched these? They are not in your completed results list on the server? Doesn't look like you've done them before.

As to what happened, you are in the best position to know this if you look back through the messages either in BOINC Manager or in the .txt files in your BOINC folder.

This message usually means that there was a glitch in communication at the time of a work request, most likely during the extremely heavy activity just after the cutover to the new S5RI series of work. Your client requested a new cachefull of work, the server tried to send it (and thought it had sent it) but your client never actually received it. On a subsequent communication at a less busy time, the client and server compared notes and worked out between themselves that the client didn't have those particular results. So the server simply announced them as being "lost" and resent them.

I think this is probably the most likely explanation. All perfectly normal - no problems.

If you still think there might be a problem, please try to give a bit more detail, particularly something like the message generated when those results were previously reported if you still think you have already done them.
