this is a strange error when I testing the current trunk with logging colation
server enabled:
{code}
[Oct 16 01:24:48.643] Server {0x2b4967f51760} WARNING: File
/var/log/trafficserver/ex_squid.log will be rolled because a LogObject with
different format is requesting the same filename

there is two problem here:
1, why the machine is not initialized?
2, what does "WARNING: File /var/log/trafficserver/ex_squid.log will be rolled
because a LogObject with different format is requesting the same filename"
mean? is that harm?
