Erm….I think I really old now, always forget where to set this, better write a post about it 🙂 . Basically, in Linux environment, usually you just need your server admin to increase the LimitRecursion in pure-ftpd.conf
First of all, check whether your server setting is how much. Usually will be 2000.
grep LimitRecursion /etc/pure-ftpd.conf
Then edit the link as below from 2000 to the amount that needed.
LimitRecursion 2000 8
Then of course restart FTP service.
