I changed the sleep interval from 5 down to 1 in successive runs, and each output looks fine; each list has the proper two subscribers. Is there a timing issue here? There appears to be some kind of race issue. There are two other reports of strangeness like this at http://mail.python.org/pipermail/mailman-developers/2008-May/020190.html and http://mail.python.org/pipermail/mailman-users/2008-May/061720.html. In both of those cases it seemed there may have been a locking failure of some kind, but I couldn't see how. See the above threads for more detail. However, locking (at least list locking at the Mailman level) doesn't seem to be involved in this case because each command process will have saved and unlocked the list and terminated before the next command process begins. I intend to test the script on two other platforms (Cygwin/Python 2.5.1, and Centos 5/Python 2.4.3) later today. Given that this script is (or should be) running the command processes serially with no contention between commands for the config.pck files, It would seem like an OS issue, but the script failure occurs on two different OS platforms already, so I'm at a loss for what the issue may be. -- Mark Sapiro [EMAIL PROTECTED]The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

While is correct as far as it goes, I forgot about VirginRunner and
OutgoingRunner sending the welcome messages. So there are other
mailman processes running in parallel accessing the same config.pck
files so list locking is involved.
I intend to test the script on two other platforms (Cygwin/Python
2.5.1, and Centos 5/Python 2.4.3) later today.
I have run a somewhat revised script on both platforms with the
following results:
Cygwin 1.5.19(0.150/4/2) on Windows XP with Python 2.5.1
No loss of members whether or not mailman is running concurrently
(3 of 3 tries with mailman running).
CentOS 5 (Linux 2.6.18-8.1.14.el5) with Python 2.4.3
No loss of members if script is run with mailman stopped.
Lost members if script is run with mailman running on 2 out of 3
tries.
So far, all the failures reported have been with Python 2.4.x and
Python 2.5.1 didn't fail, but this could also be Cygwin and
independent of Python. It would help if others could try this with
Python 2.5.x and report.
Here's the script I used. It is similar to the original, but I
parameterized several things and I added '-a' to the rmlist command.
