cPanel v11.50 cxs and pure-ftp startup/login problems

If you are running cPanel CURRENT and have just upgraded to v11.50 and have cxs installed with ftp upload scanning and pure-ftpd is not restarting correctly, you may need to run the following to ensure pure-ftpd starts correctly:

service pure-uploadscript restart

or

/etc/init.d/pure-uploadscript restart
