After enabling the debug mode I got seg fault in /usr/local/var/log/trafficserver/traffic.out

If I add more than 1 HDD ATS is reserving memory and it is killing itself in ~20GB of RAM and restarting again and again. Go check the archives for an explanation on how disk cache size correlates to RAM consumption. No errors in diags.log only in manage.log: [Dec 3 16:30:25.473] {0x7f301e55d740} STATUS: opened /usr/local/var/log/trafficserver/manager.log [Dec 3 16:30:25.473] {0x7f301e55d740} NOTE: updated diags config [Dec 3 16:30:25.475] Manager {0x7f301e55d740} NOTE: [ClusterCom::ClusterCom] Node running on OS: 'Linux' Release: '3.2.0-34-generic' Now, it sounds like you have enough memory to support these large drives. So, I can't tell from the information given why you are seeing server restarts. ATS typically would kill / restart itself only if the traffic_server process is not responding to the synthetic health checks that the system uses. -- Leif
