ch_owner: too many open files

[K.H. Cheung]

Hello all,

I am trying to chown the directory with the appropriate user with /usr/local/psa/bin/ch_owner.

It gives me an error when running the following command:
/usr/local/psa/admin/bin/ch_owner -R usersacln /var/www/vhosts/user.nl/httpdocs/folder1/

Sales: Too many open files
Segmentation fault

But it works when I run "chown -R usersacln /var/www/vhosts/usr.nl/httpdocs/folder1/".
