The default for either network retries or modem retries (I forget which, big
surprise) is 2 minutes. If there is a communications problem with the
machine (asking for exponents but not receiving them for some reason), that
would explain the timing. Also, if the machine is running unattended and

Seriously, though, if this is a widespread problem then we should consider some
sort of web-based form or automated e-mail confirmation system where the user
basically says Yes, I'm about to request a stack of exponents and I am serious

I'm not sure I understand that code
I'll forward your attempted post. I don't remember Eric's prediction, but
if true
it is quite insightful (or lucky).

Yes I suppose we will find others. The list you show is quite short
(12), we know 39 mersennes, have we investigated them all?

Eric Hahn posted a message on July 30, 2000, stating that one of
the ranges a Mersenne Prime should be found was between
2^13430227-1 and 2^13501387.
That July 30, 2000 posting by Eric Hahn included:
M#39 - 53.7390% probability - range=10987349-11013853
