I’m currently hosting two VPS instances at Hetzner, both running Ubuntu and managed via aaPanel. Recently, I’ve encountered a frustrating issue when uploading files via FTP (using Forklift on macOS):
Even for small uploads (5–6 MB), the transfer abruptly stops, and the client displays the error "Cannot allocate memory."
This started happening yesterday, and I’ve even created a new server since then to rule out configuration issues. Sadly, the same problem occurs.
Here’s the setup for my servers:
Server 1: Intel processor, 4GB RAM.
Server 2: ARM processor, 8GB RAM.
What makes this even more annoying is that I’ve resorted to using aaPanel’s internal file manager for uploads. However, this is far from ideal because:
It’s slow.
It doesn’t support uploading entire folders, and files must be uploaded individually.
Has anyone encountered this issue before or knows how to fix it? Could it be related to memory settings in aaPanel, FTP server configuration, or even something with my macOS setup?
Any help would be much appreciated! Thanks in advance!
