Hi all, I am trying to run a web-based PHP application on a CentOS 5 32-bit machine that requires me to upload large files. The machine also happens to have little RAM (256MB). I have no problem setting my upload limit ( upload_max_filesize ) to 1 GB but for some reason 2 GB or above seems to be no go. Would anybody know why? Could it be one of the many 32-bit vs 64-bit issues? Thanks. Boris.
