>Description:
The /etc/rc.subr script contains a function check_pidfile that calls _find_processes to check if a file containing a pid is referencing a running process matching a specific name.

It's due to /bin/sh 'case' struct.

Try:

#!/bin/sh
my="[tcp]"
case ${my} in
  ${my}) echo no;;
  "${my}") echo yes;;
esac


In /etc/rc.subr:
_fp_match='case "$_arg0" in
                    $_procname|$_procnamebn|${_procnamebn}:|"(${_procnamebn})")'

BTW, i don't understand why both $_procnamebn and ${_procnamebn} are there...
>How-To-Repeat:
Try to manage with an rcNG script a daemon who display in ps in "[]", ie tcpserver:

21478  p0  I      0:00,00 [tcpserver]


check_pidfile ${pidfile} '[tcpserver]'

This call doesn't returns any result.
>Fix:
In /etc/rc.subr:

-_fp_match='case "$_arg0" in
                    $_procname|$_procnamebn|${_procnamebn}:|"(${_procnamebn})")'
+_fp_match='case "$_arg0" in
                    $_procname|"$_procnamebn"|${_procnamebn}:|"(${_procnamebn})")'

Or maybe...

+_fp_match='case "$_arg0" in
                    "$_procname"|"$_procnamebn"|"${_procnamebn}:"|"(${_procnamebn})")'
