If your buffer size is 50 blocks but you do a fetch and flush at 40 blocks, the
last 10 blocks in your buffer are very old. This is the "FIFO/LIFO" debate that
continues on this list, and will probably continue until the v3 clients are
released, which will hopefully address this problem.

If this machine has an Internet connection of any kind, either by dialup or
direct network, it should be configured to fetch and flush at least daily. If
this machine is offline, I would recommend updating at least monthly. (The
current estimate for reissues is indeed 6 weeks, but this can only decrease as
d.net's processing power increases.)
