Eero,
I've got 4 GB of swap. At the moment all 4 GB less 100 MB of it is available. That logically should be enough to allow me to upload a 2 GB file, I would think.
Looking at the bugtracker: http://bugs.centos.org/view.php?id=3118
"PHP is not built with large file support on 32 bit x86, probably other 32 bit platforms, all releases of CentOS 4 Additional Information I verified that upstream does not have this problem. It is severe enough for my use (scientific processing) that I am changing OS."
While the report is for CentOS4, it may be related to your problem.

OK, at least part of it could have been related to the machine being 32 bit. I am currently playing with a 64 bit machine. I can set my upload_max_filesize = 2G and that works fine; however, post_max_size is a problem. if I set it to 2 G it seems to fail (no POST transactions go through, it seems). If I set it just a tad lower (what I have now is post_max_size = 1948M ) it works fine. So the cutoff limit is somewhere in the 2G neighborhood.
Any idea why that would be? Is there a parameter anywhere that limits how far post_max_size may go? The total memory setting I use is way above ( memory_limit = 6G ) and that seems not to cause any issues.
Thanks for your advice everybody.
Cheers,
Boris.
Here's what further research on the topic indicates: it is unclear whether or not PHP can handle files in excess of 2 GB in size. If it can that would still be a relatively recent achievement. So in short it sounds like - at this point in time - it may be safest simply not to try to handle files that size.

Continuing the search...
Looks like the LimitRequestBody directive for Apache may make some difference: http://httpd.apache.org/docs/2.0/mod/core.html#limitrequestbody
Set mine to 5B ~ 5GB. Looks like I can at least submit a 2.4 GB upload request now.
