64-bit executables

[ARC1450]

I've got a nice Cacti install going on a 8-core box with 16GB of RAM.

All goes decently, except I cannot used any more than about 4 GB of RAM because the programs (Apache, PHP) are 32-bit executables. Now, normally this wouldn't bug me, but when using boost I start getting to that 4GB limit and PHP/Apache sometimes gets very unhappy using more RAM.

Does anyone have any resources where I can push the Cacti install to total 64-bit?

Until the Apache and PHP groups provide official x64 binaries, they cannot be included in the Windows Installer. Yes, there are unofficial x64 builds of each you can try though...

[ARC1450]

Ahhh, okey dokey.

Have you had any success with the unofficial builds?

My Cacti installation at work is small enough, I'm not pushing the 32bit limits so haven't tried.

[ARC1450]

All righty.

Have you tried PHP 5.3.x with 0.8.7i? If it's a minor switchover with no real bad things happening, I might try using the 64-bit downloads and see what happens, but if it is too much of a pain, forget it.

If you go with php 5.3, also upgrade to mysql 5.5. Yes, Cacti works with both of these versions.

Hey, guess what?

This exercise was absolutely pointless! PHP can't allocate more than 4095M. As soon as you try to tell it to allocate 4096M, it crashes.

Come to find out, the conversion is done with 32-bit integers, even in an x64 compiled binary.

So, good thing I didn't install 64-bit binaries. . .it wouldn't have done any good anyhow.
