Periodic Failures

I'm still trying to find a good way to pull Hotmail mail down to my Linux
mail system.  I used Hotwayd for several months... which I have to admit
there's some things about it that I like better than gotmail.  For
instance, I kind of preferred the proxy POP3 server approach.  But, in the
end, it failed to retrieve mail for an entire week, with no reports of
errors.  So, I decided to give gotmail a try.

It's been running for about a month.  Usually it works with out flaw. 
I've wrapped it in a simple script that eats all output, unless an error
occurs. This way, I get an e-mail from Cron only when a gotmail fails for
some reason.  Most of the time, it runs with out an issue... but
occasionally I get reports like the following:

---

Getting hotmail index page...

gotmail died with message: Could not isolate folder index location

Any ideas why this occurs?
