If you want to look at where your memory is being used I would suggest running:
[bcall@homer ~]$ ps aux --sort -rss | head and [bcall@homer ~]$ sudo kill -SIGUSR1 $(pidof traffic_server) [bcall@homer ~]$ tail -100 /usr/local/var/log/trafficserver/traffic.out If you can paste the output of those commands it would help diagnose the issue.
