You should have a log-message "main: MAX_PROC (150) reached".
However, > 100 is huge. What's the average mail/hour (or mail/minute) this

What is the average delay when a client connects to an smtpd and policyd-weight
answers?

As you are running Gentoo, which log files did you check. Gentoo might send
debug messages to /var/log/debug.log
# date > debug-pr.txt 2>&1
# /path/to/policyd-weight -k restart >> debug-pr.txt 2>&1
# echo "/path/to/policyd-weight -k restart -- done" >> debug-pr.txt 2>&1
# bash
# grep "weight\[" /var/log/mail.log /var/log/debug.log >> debug-pr.txt 2>&1
# exit
(that bash call is to make sure that no zsh is used. zsh does sometimes so some
weird globbing or escapes meta-chars where it shouldn't escape them)
