Comment 31 for bug 1246245

I can confirm this bug. I just ran into it on a production machine. The bugfix is documented in this thread and here: http://stackoverflow.com/questions/23666697/proftpd-killed-signal-15-error-how-to-fix-logrotate-restart-error

It's killing FTP-Servers since 2013. And it's a one-line fix. If I had write access, I would patch it myself.

It would be totally awesome if anyone could fix it soon.
