That is probably the problem. The kernel will be waiting for rclone for 10 minutes and it will timeout.
You can try setting this flag
--daemon-timeout Duration Time limit for rclone to respond to kernel (not supported on Windows) (default 0s)
Say --daemon-timeout 15m which might help. (The default is 10 minutes on macOS). There is an upper limit for it which I can't remember but it isn't very big. You may also be able to turn off this timeout using --daemon-timeout 0 which might also be worth a try.
When stuff goes wrong in kernel space, the system tends to suffer.
