Server was running fine; short: scheduling was in FIFO mode because of WU deadlines approaching and the need for homogeneous redundancy.

From 24-06-2015 till 03-07-2015 not a single WU got validated (so validator down) and nobody received new work (so scheduler off), according to BOINCStats. FreeDC has these dates as from 23-06-2015 till 02-07-2015 due to different cut-off moments. As this unfortunate event took place before, during and after a challenge, you missed out on a great many of volunteers who could have help achieving the desired homogeneous redundancy long before it took place now.

Hi,

nope not realy; the WUs in question were mapped to an OS+CPU combo that was rare and visited this project only once => no new WUs until these were done (or reset manually or because of dead lines not met) => no other WUs validated. Scheduler was running as intended, so was validator.

How to avoid this in future?

Now because we cannot remove homogeneous redundancy and we have no more access to build environment for Apple Mac Intel (to build and to test), we decided to stop supporting that platform in future. This means less manual interventions needed when a rare OS+CPU combo is encountered. The Apple platform show the highest faile rate here in this project (due to graphical library dependancies and changes to OSX) and the fewest hosts.
