[Mailman-Users] Locks

[Gergely Soros]

We're using Mailman 2.0 on a Redhat machine with Sendmail. Occasionally upon accessing the
web admin interface some lockfiles remain and they need to be deleted. At this time there is one
sleeping python process:

------------------------------------
[root locks]# ps -AHf
..
httpd     3564   424  0 10:24 ?        00:00:55     /usr/sbin/httpd -f /etc/httpd/conf/httpd.conf
httpd    18038  3564  0 15:42 ?        00:00:00       /usr/bin/python -S /home/mailman/scripts/driver admin
..
------------------------------------

The /locks directory shows locks with future dates:

------------------------------------
[root locks]# ls -lsa --full-time
total 8

[root locks]#  date

------------------------------------

Today I have deleted some lockfiles while delivery to a list of +10.000 took place and 18 copies of the 
message were delivered before I emptied the queue. Mailman and httpd error logs are not touched.
Is there any connection between deleting the lockfiles and multiple deliveries? Are lockfiles with
future dates normal? Is deleting lockfiles a bad thing?
