I tried to use 2.1.2. But it doesnt seem to run for me.

./bin/trafficserver start
says ok
but only traffic_cop is running.

I tried to start traffic_manager by hand. This is the output.
[root@c1b14 ats2]# ./bin/traffic_manager
[E. Mgmt] log ==> [TrafficManager] using root directory '/usr/local/ats2'
[Sep 15 14:17:40.146] {140131646002992} STATUS: opened

There is not much in the manager.log.

./bin/traffic_server runs ok, but I cant use the traffic_shell. It
complains about traffic_manager errors.

ERROR: Timed-out while communicating with traffic_manager.
       Ability to make configuration changes depends on traffic_manager.

I am using it as an explicit proxy and after starting traffic_server
it does serve the request and I even get a hit on subsequent request,
but after sending a few request it started giving the following error
and died eventually.

Any thoughts ?
