1. Memory exhausted issue at download a large CC has been fixed by reading and sending the download file in chunks, 3k at a time.
SVN revision: 10170
Affected: include/classes/zipfile.class.php

2. The blank page is given at importing a large common cartridge is because the script stops at unzipping the uploaded file. In more detail, stops at include/classes/pclzip.lib.php, line 3888. Function gzinflate() ceases without any return. This issue happens especially when there's a large file in CC. If the zip file is composed of many small files, should be ok. pclzip creators realize the issue as well. See: [^]

The solution is to increase memory_limit in php.ini. To handle a 25M video in CC, memory_limit needs to be around 80M.

A FAQ in handbook needs to be set up to answer this type of user inquiry.

Sort of fixed. PclZIP needs reworking to better use of memory. It zips into memory instead of temp files, thus is very memory intensive. A FAQ has been posted describing the issue with biug files.
