I've noticed that few results which I downloaded recently were sent to six computers.

Is this intentionaly or?

Unfortunately, you haven't given examples, so here's a few ideas:

The quorum is set to four to give a better chance of a valid result at the first attempt. i.e. Four units will be issued immediately.

Then, in no particular order:

Units past the deadline will be reissued.

Units that have failed on the client with some form of computation error, or have been aborted by the user, or have failed for some other reason will be reissued.

If too many results are invalid the unit may be reissued, until ten results have been <B>returned[/b].

Look at the WUs in question, and see what results have been returned by other people with the same WU.

[Edit] I just had a closer look at some of my WUs - it looks like the quorum is now six. This seems like overkill to me...

Here's an example:

http://lhcathome.cern.ch/workunit.php?wuid=375970

It's been sent to six hosts and none have returned as error.

qourum is three, sent units five. If we get down to very few WU we will increase the number of results (not the number needed for a quorum) to hopefully decrease the turn around time for a study.
