Question

My php script running on CentOS 5.6 and PHP 5.2.12 using ZipArchive() and successfully creates .zip files over 1.6Gb but not for a larger archive of 2GB or larger - PHP abor

Answer 1

It could be many things. I'm assuming that you have enough free disk space to handle the process. As others have mentioned, there could be some problems fixed either by editing your php.ini file or using the ini_set() function in the code itself.

How much memory does your machine have? If it exhausts your actual memory, then it makes sense that it would abort regularly after a certain size. So, check the free memory usage before the script and monitor it as the script executes.

A third option could be based on the file system itself. I don't have much experience with CentOS, but some file systems do not allow files over 2 gb. Although, from the product page, it seems like most systems on CentOS can handle it.

A fourth option, which seems to be the most promising, appears if you look at the product page linked above, another possible culprit is "Maximum x86 per-process virtual address space," which is approximately 3gb. x86_64 is about 2tb, so check the type of processor.

Again, it seems like the fourth option is the culprit.
