The child process handles the communication to the manager/proxies. These will go away once the conversion to broker is done.

Munin is crazy easy to get up and running and does the job, but it's not the best monitoring system out there. You can also use things like sar to collect data and use something else to graph it.

Ah.. if your network sees a lot of scan traffic, scan.bro could be what is killing your cluster.
If you run these commands, what values do you get?
wc -l conn.log
cat conn.log|bro-cut id.resp_p |fgrep -cw 23
cat conn.log|bro-cut history|sort|uniq -c |sort -rn|head
