I have a systemd service that sets
MemoryMax. If I look under its cgroup in
memory.limit_in_bytes file matches the limit set by
MemoryMax, but where do I find the value set by
MemoryHigh? There is a file named
memory.soft_limit_in_bytes so I expected it to be that, but its value is always 9223372036854771712 (8 EB?).
The doc for MemoryHigh says
This controls the "memory.high" control group attribute
but there is no file with that name.
This is on Ubuntu 18.04.
