I checked the status pages for ESP a little while before the results were reported and noticed that the pending tests only went back about 12 hours -- everything before that (including these 10) were missing.
Looks like they weren't missing only from the status page, but were completely gone from the server.
I doubt I'm the only one who was affected by this.
Perhaps even worse, it looks like there was some data lost. It would be a shame if some of the rejected results knocked off a half dozen of the remaining k's!

This should be an easy fix for Lennart. The problem is that the tests are expiring too quickly. Expiration is on a "per test" basis, but since one can grab multiple workunits at a time, the expiration parameter needs to account for it. | |

I don't think that's the problem here, unless the expiration time was just lowered, and lowered significantly. Judging by the published table of expiration times, the timeout should be several days whereas the results were returned in 16 hours. Furthermore, pending tests in the 30+ hour range have been common on the pending test page.
There appears to have been some sort of reset of the project. The server status page changed and no longer shows the 20 or so k's for which primes have been found.

I agree with Michael... I believe this is a result of loading the 1.4M tests and/or resulting server reset. All my tests < 1.4M had this problem too, meanwhile my 2nd core was working on > 1.4M tests and had no problems..

Hopefully one of the admins can let us know what we need to do, if anything.

If that is the case, then Lennart must have reloaded the database. | |

I am sorry But I needed to clean it up ! I had to change HD in that computer.
The server was empty and there was about 1M candidates in DB so I decided to clean it and start from scratch from 1.4M
I did lower delay and moved my computers over to get it done fast.
I'll add the points to DB for the work.
