mod_measure_process: Report the enforced limit The soft limit is what the kernel actually enforces, while the hard limit is is how far you can change the soft limit without privileges. Unless the process dynamically adjusts the soft limit, knowing the hard limit is not as useful as knowing the soft limit. Reporting the soft limit and the number of in-use FDs allows placing alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

summary: Block s2s connections based on admin blocklists
...

This module uses the blocklists set by admins for blocking s2s
connections.

So if an admin blocks a bare domain using [Blocking Command][xep191]
via [mod\_blocklist][doc:modules:mod_blocklist] then no s2s connections
will be allowed to or from that domain.
