Initial Comment: Mailman 2.1.11 Python 2.4.4 OS Solaris 2.11 Hi, I have been able to reproduce this bug consistently by running the replicate_bug script: replicate _bug is the following: #!/bin/sh /usr/local/mailman/bin/rmlist testlist1 /usr/local/mailman/bin/rmlist testlist2 /usr/local/mailman/bin/rmlist testlist3 /usr/local/mailman/bin/rmlist testlist4 /usr/local/mailman/bin/rmlist testlist5 /usr/local/mailman/bin/rmlist testlist6 /usr/local/mailman/bin/newlist -q -e url.domain.com testlist1 list-admin@domain.com testpwd /usr/local/mailman/bin/newlist -q -e url.domain.com testlist2 list-admin@domain.com testpwd /usr/local/mailman/bin/newlist -q -e url.domain.com testlist3 list-admin@domain.com testpwd /usr/local/mailman/bin/newlist -q -e url.domain.com testlist4 list-admin@domain.com testpwd /usr/local/mailman/bin/newlist -q -e url.domain.com testlist5 list-admin@domain.com testpwd /usr/local/mailman/bin/newlist -q -e url.domain.com testlist6 list-admin@domain.com testpwd echo "foo@bar.com" | /usr/local/mailman/bin/add_members -r - testlist1 echo "foo@bar.com" | /usr/local/mailman/bin/add_members -r - testlist2 echo "foo@bar.com" | /usr/local/mailman/bin/add_members -r - testlist3 echo "foo@bar.com" | /usr/local/mailman/bin/add_members -r - testlist4 echo "foo@bar.com" | /usr/local/mailman/bin/add_members -r - testlist5 echo "foo@bar.com" | /usr/local/mailman/bin/add_members -r - testlist6 echo "boo@foo.com" | /usr/local/mailman/bin/add_members -r - testlist1 echo "boo@foo.com" | /usr/local/mailman/bin/add_members -r - testlist2 echo "boo@foo.com" | /usr/local/mailman/bin/add_members -r - testlist3 echo "boo@foo.com" | /usr/local/mailman/bin/add_members -r - testlist4 echo "boo@foo.com" | /usr/local/mailman/bin/add_members -r - testlist5 echo "boo@foo.com" | /usr/local/mailman/bin/add_members -r - testlist6 After a short wait the following output is received: Subscribed: foo@bar.com Subscribed: foo@bar.com Subscribed: foo@bar.com Subscribed: foo@bar.com Subscribed: foo@bar.com Subscribed: foo@bar.com Subscribed: boo@foo.com Subscribed: boo@foo.com Subscribed: boo@foo.com Subscribed: boo@foo.com Subscribed: boo@foo.com Subscribed: boo@foo.com foo@bar.com receives 6 confirmation emails, as boo@foo.com does. So far so good. At this point testlist1-6 each should contain 2 subscribers: foo@bar.com and boo@foo.com BUT /usr/local/mailman/bin/list_members testlist1 /usr/local/mailman/bin/list_members testlist2 /usr/local/mailman/bin/list_members testlist3 /usr/local/mailman/bin/list_members testlist4 /usr/local/mailman/bin/list_members testlist5 /usr/local/mailman/bin/list_members testlist6 invariably produce some random combination in which one or more of the subscribers are missing: for example: boo@foo.com foo@bar.com foo@bar.com boo@foo.com foo@bar.com foo@bar.com foo@bar.com boo@foo.com foo@bar.com in which three instances of boo@foo.com are missing... No Errors in any Mailman log. Thanks in advance for your help. Please let me know if you need additional details. Regards, Max ----------------------------------------------------------------------
