Cloud9 - EXTREMELY High CPU Usage

0

Lately Cloud9 has been using an insane amount of CPU, to the point nothing will load. The node process (vfs-worker) will randomly start using 100-200% CPU and not stop until I killall node or reboot. This is on a Fresh Ubuntu install with a fresh Cloud9 install. I've switched servers 3 times, started fresh every time and still having the issue. Currently I'm on a 6 core VPS with 16gb of RAM and NVMe drives with nothing else running - the machine has no speed issues until I pull up Cloud9 and then this happens.

top output currently (this is typical of the issue):

Dear Customer,

Generally speaking, CPU usage percentages higher than 100% are normal for multi-core machines, meaning that the issue might be caused by other factors.
