The best way to restart Mailman depends on whether just mailmanctl or also all the qrunners die. If all the qrunners are gone, you can just run Mailman's "bin/mailmanctl start" or whatever cPanel voodoo starts the Mailman service. If there are still qrunner processes running when mailmanctl dies, see the FAQ at <http://wiki.list.org/x/_4A9>.

As far as I know, this is not something that cPanel Mailman does by default?

[...] The underlying issue here is that Python's MySQLdb was apparently installed by root in a way that the the Python egg cache directory is not writeable by the Mailman process. You can get rid of the above errors by simply removing /usr/local/cpanel/3rdparty/mailman/lists/mailman/extend.py and perhaps any other /usr/local/cpanel/3rdparty/mailman/lists/*/extend.py files, but this will defeat your use of MysqlMemberships.py, but since it doesn't work anyway, and maybe is only installed for the site list, that shouldn't be too much of an issue. Also, please read the FAQ at <http://wiki.list.org/display/DOC/Mailman+and+CPanel>. Finally, it is not clear to me that the above error is from the crash. It seems to me it would occur whenever mailmanctl starts. Is this all that's in Mailman's error log? What's in Mailman's qrunner log? -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
