Bug#804762: proftpd version 1.3.5-1.1+deb8u1 bug

[Aurel Mihai]

Package: proftpd-basic
Version: 1.3.5-1.1+deb8u1

In /var/log/proftpd/proftpd.log:

ROOT PRIVS: unable to seteuid(): Operation not permitted
ROOT PRIVS: unable to setegid(): Operation not permitted
RELINQUISH PRIVS: unable to seteuid(PR_ROOT_UID): Operation not permitted

I am using Debian 8.2, kernel 3.16.7-ckt11-1+deb8u6

I belive this is the proftpd bug #4091
