Dear project Team!
You started new batch of WUs with:
1. minimum quorum - 3;
2. initial replication - 3;
3. max # of error/total/success tasks - also 3, 3, 3!!! or ZERO possible attempts, if at least 1 task in WU will end with computation error, download error, user abort etc.
So, just take a look to first results of this new "strategy"...
I observed my nearest host only:
- from 32 tasks 6 got status "Cancelled by server" or "Completed, can't validate";
- 20% WUs are lost;
- approx. 170 hours of CPU time is wasted (in 6 lost WUs)...
Is this simple mistake by changing server's configuration (still hope for this)?
Or is this Your new strategy? If so, I do not understand You...

I will try and get help to stop the project, cancel WUs, and restart.
I can't do this myself, and it is a holiday weekend. We shall see.
Eric.

please see http://lhcathomeclassic.cern.ch/sixtrack/forum_thread.php?id=3921&postid=27279

Thank You, I know this problem.
And I have NOTHING against raised quorum - the project knows here better than all of us, which level of confidence is mandatory at the moment.
I just reported an another problem.
Eric, Thank You for fast reply. Happy Holiday!
