Docker can become unresponsive, but containers continue to run

Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.

A lot of back and forth over the last week. Project manager says they can't reproduce the issue (although how long they tested for is unclear). Last reply I got today:
I forwarded your entire message and copied ASUSTOR's CEO.
So, hi Shawn Shu apparently...

If the NAS is being used as normal storage then there should be no issue unless:

1. There's some huge backup jobs running concurrently.

2. NAS used as a web/file server handling lots of traffic.

3. Heavy torrenting.

4. Worst all above combined.

I believe this is just the default ulimit for normal usage. To go beyond, the ulimit needs to be raised accordingly, to a point that it wouldn't compromise the performance/security. It would be great if Asustor would provide an option to increase the default system wide soft/hard ulimit at boot because there's no way of currently modifying it without patching the initramfs. Of course one could modify them i.e. using the simple script I've provided earlier.
