[Mailman-Users] List Sync Problem

[ISE]

Hello,

I have compiled a script based upon the great feedback from Jon Carnes and
the Mailman FAQ that generates a "main" which consists of all the
subscribers from a set of lists.  This script then  syncs this list with a
.htpasswd file.  My script works fine via a hourly cron job minus one
glitch.  Ever few days or so (this does not happen at any consistent time)
when the script is filtering through the list set, it come back with zero
list subscribers.  Following this, the script then updates the main list.
Because It comes back with zero subscribers, the main list's members are all
removed.  An hour later when the job is run again, the script locates all
the expected list members from the list set and then re-subscribes everyone.
The main problem with this is that all the re-subscribed members are
assigned new passwords, ultimately making my attempt to sync this list to a
.htpasswd file unfruitful as the list members can never be certain of what
their password is.

I have included the script below.  I don't think the problem is with the
script, but perhaps has something to do with Mailman.  Any ideas?

Thank you,
