[Mailman-Users] Updating MM 2.1.2 -> 2.1.5 "stucks"

[Frank Thommen]

Hello list members,

while updating MM from 2.1.2 to 2.1.5, the process of updating gets
stucked at one specific maillist.  I added a 'print mlist' in 'def
update_pending()' after
'for listname in Utils.list_names():
        mlist = MailList.MailList(listname)'

to know where it happens:


# bin/update
Upgrading from version 0x20102f0 to 0x20105f0
getting rid of old source files
Updating mailing list: XXX
  [...updates all lists with one "could not acquire lock" message...]
Updating Usenet watermarks
- nothing to update here
Updating Mailman 2.1.4 pending.pck database
WARNING: Ignoring duplicate pending ID: 7544.
  [..warns for many more "pending IDs"..]
<mailing list "list1" (locked) at 4b8300>
<mailing list "list2" (locked) at 4bbdf0>


...and here the process waits/loops forever (at least more then three
hours...).  I ^C-stopped the update several times, but it gets always
stucked at the same list.



Two questions:

 * Any hints, what the problem could be and how it could be solved?
   (please be very specific if it comes to coding, I'm a Python
   dummy)

 * I've stopped our maillist system with 80 lists:  Can I restart
   MM 2.1.2 for the time being after this partial update or will
   that finally corrupt my system?


Thank you very much in advance for any hints.

   frank
