Hi, 

We are running
[root@<machine> ~]# pkg info | grep traff
trafficserver-6.2.0            Fast, scalable and extensible HTTP proxy server

on one machine:
[root@<machine> ~]# uname -a
FreeBSD portos.sr.se 10.3-RELEASE-p7 FreeBSD 10.3-RELEASE-p7 #0: Thu Aug 11
18:38:15 UTC 2016    
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

and ATS is crashing at least once a day with the following error in
manager.log:

This of course alleviates the memory leak we also are experiencing in v6.2.0,
but I have already created a PR for that earlier :)
