--- Comment #1 from Fabian Keil <fk at fabiankeil.de> ---
I could not reproduce the problem on ElectroBSD based on 11.4-STABLE r368530.

The cp fails with "No space left on device" as can be expected from the small
pool size.

I'm wondering if you're running into ggated recv_thread() queuing incomplete
WRITE requests.

I've reported this and other ggate-related issues in 2015 to
<security-officer at FreeBSD.org> but AFAIK it still hasn't been fixed upstream.

You could try the patch from:
