----------------------------------------
perhaps the core dump was generated not for that situation which I described
above.
The userid is 108.
here is the message from traffic.out file when ATS died:
traffic_server: Segmentation fault (Address not mapped to object [0x8])

> Hello ,
> I manage to compile ATS 5.2.0 for ubuntu 14.04 LTS 64bit.
> One of the ATS instances in some unknown surcumstances is being crashed when
> I put nodes in cluster mode.
> How to reproduce.
> ===============
> You have to install 2 ATS on diffierent machines. Put the ATS instances into
> cluster mode and load them with http requests.
> Core dump output
> ==============
> Type "apropos word" to search for commands related to "word"...
> Reading symbols from /usr/lib/debug/usr/bin/traffic_server...done.

> Temporarly Solution
> =====================
> Now as temporarly solution we disabled cluster mode and put haproxy in front
> of our ATS nodes.
