http://magento.stackexchange.com/questions/34015/magento-1-9-php-5-6-use-of-iconv-internal-encoding-.... You may see something like the following that is filling up your system.log:
ERR (3): Deprecated functionality: iconv_set_encoding(): Use of iconv.internal_encoding is deprecated in /var/www/vhosts/example.co.nz/httpdocs/lib/Zend/Locale/Format.php on line 1050 ERR (3): Deprecated functionality: iconv_set_encoding(): Use of iconv.internal_encoding is deprecated in /var/www/vhosts/example.co.nz/httpdocs/lib/Zend/Validate/Hostname.php on line 553
