Description

Start up Traffic Server:

    0 26950     1   0 10:13AM ??         0:00.01 /opt/ats/bin/traffic_cop
   -2 26951 26950   0 10:13AM ??         0:00.02 /opt/ats/bin/traffic_manager --bind_stdout /opt/ats/var/log/trafficserver/traffic.out --bind_stderr /opt/ats/var/log/trafficserver/traffic.out
   -2 26952 26951   0 10:13AM ??         0:00.08 /opt/ats/bin/traffic_server -M --bind_stdout /opt/ats/var/log/trafficserver/traffic.out --bind_stderr /opt/ats/var/log/trafficserver/traffic.out --httpport 8080:fd=12

Now restart it using traffic_line -S followed by traffic_line -U:

    0 26950     1   0 10:13AM ??         0:00.01 /opt/ats/bin/traffic_cop
   -2 26951 26950   0 10:13AM ??         0:00.05 /opt/ats/bin/traffic_manager --bind_stdout /opt/ats/var/log/trafficserver/traffic.out --bind_stderr /opt/ats/var/log/trafficserver/traffic.out
   -2 26967 26951   0 10:13AM ??         0:00.12 /opt/ats/bin/traffic_server -M --httpport 8080:fd=20

Note that we lost the --bind_stdout and --bind_stderr options.
