"Upload certificates" are a mechanism that keeps bad guys from DoS'ing your upload servers (note: such an attack has never happened, as far as I know).

We're changing the format of upload certificates, and we're starting to test a version of the client for which old-format certificates won't work. Volunteers testers won't be able to upload completed jobs, and they may complain to you.

I suggest that all projects disable upload certificates. To do so, add the following to your config.xml file:


To resume using upload certificates, if you wish:

1) upgrade to the current server source code (from trunk)
2) wait for all jobs with old-format certificates to be dispatched
3) re-enable certificates by removing the above lines.

Let me know if any questions.

Primabonica also is reported as "offline" on the BOINCSTATS site page.

Thanks for the update. An additional infrastructure check, I haven't seen any of the credits show up on BOINCSTATS, are they being reported but just backlogged due to volume?

Thanks again.

I have a growing number of completed WUs that are stalled "completed, awaiting validation". The minimum quorum for each WU is "1" so I assume this is a backend stall (possibly the validator?).

Here's a pointer to the WUs:


thanks in advance for any assistance with this issue.
