The process control (PCNTL) extensions are required in case you want to interrupt long running commands

[WNYmathGuy]

So each time a poll launches or a vote is cast, this message prepends it:

The process control (PCNTL) extensions are required in case you want to interrupt 
long running commands - see http://php.net/manual/en/book.pcntl.php

My PHP.ini file has this:

; This directive allows you to disable certain functions for security reasons.
; It receives a comma-delimited list of function names.
; http://php.net/disable-functions
disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wifcontinued,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_get_handler,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,pcntl_async_signals,

I'm not sure I want to enable things said to be disabled for security reasons, but I also don't want that message each time a poll is in process.

Can I disable the message?

Well, as you can read in the message, the extension allows you to stop long running commands. So yeah, since you want to use CLI this way, it's okay to enable/allow those functions.

I'm very novice with PHP. I couldn't find a definite enable_functions or a allow_functions so I just commented out the line for the PHP.ini of the Nextcolud's virtual server. That did the trick.
