DSM 7 [ERR] issue for channels user setting nofile limit

2021/07/11 14:07:31 [ERR] Could not set nofile limit: operation not permitted

I have yet to experience any issues, but wonder if channels user could hit some limit at some point.
So what are the limits supposed to be?

This is what ulimit looks like now:
