Installation / Re: Compiler requires 512 MB RAM + SWAP

« on: May 28, 2024, 04:09:56 AM »

I ran the installer on Almalinux 8 and everything went fine until it got to the php compile part in cli and gave me the error that I needed this:

Compiler requires 512 MB RAM + SWAP

Ummm, I have an Intel i7 DDR3 16GB ram offshore server so I DO have more than 512mb!!!

[root@dragon ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:           15Gi       418Mi        13Gi       9.0Mi       1.9Gi        14Gi

Hello,

The error message is misleading in your case. You definitely have enough RAM (15Gi) and swap (1.0Gi) for the PHP compilation process.

Here's what might be happening:

Incorrect Minimum Requirement: The installer might have outdated information about minimum requirements. Modern compilers should function with much less RAM, especially with ample swap space available.

Temporary Spike in Usage: It's possible during compilation, memory usage might spike momentarily exceeding 512MB. This wouldn't be a problem with your 16GB RAM.

Let's troubleshoot the compilation error:

Check Actual RAM Usage:  Run top command during compilation to monitor real-time memory usage. It's unlikely to reach even close to 512MB.

Ignore the Error (if compilation continues): If the error pops up but compilation proceeds without crashing, it's safe to ignore it. The system is using swap effectively.

Increase Swap (if necessary, unlikely): If the compilation fails due to memory limitations (shown by top), consider creating a temporary swap file. However, with 16GB RAM, this is highly unlikely to be needed.

Update Installer (if possible): If the issue persists, check if the installer has an update available. It might contain a fix for the outdated minimum requirement message.
