Disable rate-limiting in rsyslog v5
If you are here, you might be getting error messages like
imuxsock begins to drop messages from pid 29233 due to rate-limiting
in your /var/log/messages. rsyslog v7 has this disabled by default but rsyslog v5 has this enabled.
To disable it, add
$SystemLogRateLimitInterval 0
$SystemLogRateLimitBurst 0
to your /etc/rsyslog.conf
.
