Okay, I've got the file now and have found the false primes in there. But...the news is not good. I found three distinct machines that produced these results:
Code:

[2009-12-06 07:03:16 GMT] 2463*2^170838-1 received by Email: sm5ymt@*******.**  User: sm5ymt  Client: 96 Program: llr  Prover: llr  Residue: PRIME

[2009-12-07 20:01:51 GMT] 2505*2^154470-1 received by Email: sm5ymt@*******.**  User: sm5ymt  Client: 96 Program: llr  Prover: llr  Residue: PRIME
On is from client "6", two from "96", and one from "150". The most reasonable conclusion would seem to be that all three are bad (or at least were at the time they produced these results--either that or Lennart's house got hit with a real whammy of cosmic rays around that time ).

Edit: I just thought of something. Lennart, do you name your clients individually per core, or per machine? If those are all cores of the same machine, then that might explain why there appeared to be three problematic clients.
