ProFTPd unable to seteuid

Question

i'm trying to figure out this problem:

2014-04-07 14:00:58,628 srv proftpd[10143] srv (pfsense.localdomain[192.168.0.1]): FTP session opened.
2014-04-07 14:01:13,779 srv proftpd[10091] srv (pfsense.localdomain[192.168.0.1]): Preparing to chroot to directory '/srv/user1'

2014-04-07 14:01:13,782 srv proftpd[10091] srv (pfsense.localdomain[192.168.0.1]): FTP session closed.

I have made a folder on my filesystem 'srv' with sub folders like 'user1', 'user2' and so on.

drwxrwxrwx  19 root root  4096 Mar  5 20:05 srv

Each user has their home directoty set to 'user1', 'user2' and so on.

drwx---r-x 189 user1   users     4096 Apr  3 11:34 user1

I had a similar problem and corrected it by setting UseIPv6 to off in /etc/proftpd/proftpd.conf
