<![CDATA[FOG hangs on "... free base memory after PXE unload"]]>I’m having a problem with some of my FOG nodes. I’ve updated my custom CA certificate and wanted to issue it to my storage nodes, which have been working without any problems for around a year now, after changing the required files, restarting the apache2 service, and recompiling the iPXE binaries it suddenly stopped working.

I am able to boot with UEFI, but BIOS hangs on “… free base memory after PXE unload”. Tried various files (undionly.kpxe, .kkpxe, ipxe.kpxe), but no luck.

Screenshots from two different storage nodes, the latter of which has not been updated (and works). Same VM, nothing apart from the VLAN tag changed in between:

Thank you for all the help in advance.

If it’s just a “saying” I can understand that but from a technical standpoint what this means is completely different and would need logs. If all you mean is the machine in quesiton is hanging, that’s a different issue altogether. I highly doubt the whole FOG Server is crashing.

I had the same problem as you and got stuck at the same step.
It’s the HTTPS configuration that’s causing the FOG server to crash.
Try doing a clean reinstall on the stable branch without configuring HTTPS.

I haven’t been able fully test these changes on physical hardware, so I pushed them to another branch. Please clone the repository and change the branch like this before installing:

git clone https://github.com/fogproject/fogproject.git
cd fogproject
git switch ipxe-bios-test

Let me know if it works out for you.

I’ve updated the iPXE on my proxmox server, still hangs on this message. Other VMs work fine, as they did with the older iPXE version.

The newest version, as of 10 minutes ago when I built it, is 1.21.1+ (g21b5b).
I may be wrong, since I don’t use my own custom certificate, but you probably need to rebuild your iPXE with the new certificate.
