TASK ERROR: memory size (65536) must be aligned to 2048 for hotplugging

I have created a VM through the GUI and using "qm create" and "qm set". I want to assign it 64 GB of memory. Here is the conf file:

agent: 1
bios: seabios
boot: order=scsi0;ide2;net0
cores: 4
cpu: host
hotplug: disk,cpu,memory,network
ide2: truenas:iso/golden2.iso,media=cdrom,size=1011M
memory: 65536
meta: creation-qemu=8.1.5,ctime=1712002754
name: gda-geo02.slc.csswx.nas.faa.gov
net0: virtio=BC:24:11:C4:58:9C,bridge=vmbr1,firewall=1
numa: 1
ostype: l26
protection: 0
scsi0: truenas:10601/vm-10601-disk-0.qcow2,discard=on,size=41G
scsihw: virtio-scsi-single
smbios1: uuid=6164e4e2-6977-4489-ade6-89ff01e562e8
tags: csswx-virt2;gda;rail
vcpus: 4
vmgenid: 25033a81-33ee-4e70-9e3c-75134d97d0dd

65536 is a multiple of 2048 (32).

When I try to start the VM I get this error message:

TASK ERROR: memory size (65536) must be aligned to 2048 for hotplugging

Since 65536 is a multiple and is allowed in the GUI, what is the real issue?

Thanks!

Turning off memory hotplugging allows the VM to start. Is there a limit to how much memory is allowed for hotplugging?

This thread might be of interest. There is an issue with certain amounts of hotplug memory: https://forum.proxmox.com/threads/problem-with-hotplug-and-64gb-ram.73621/post-328652
