Subject traffic_server get a segfault when ICP is enabled
Date Fri, 22 Oct 2010 09:53:35 GMT
I have a ts-2.0.1 stable installed on a Linux node. It works fine in single mode. But when
I enable ICP, traffic_server gets a segfault during start. 

I have a line
ts1:10.161.29.89:2:8080:3130:0:0.0.0.0:1:
in icp.config

(10.161.29.89 is another node running ts-2.0.1) 

and 
CONFIG proxy.config.icp.enabled INT 2
CONFIG proxy.config.icp.icp_interface STRING eth1
CONFIG proxy.config.icp.icp_port INT 3130
CONFIG proxy.config.icp.multicast_enabled INT 0
CONFIG proxy.config.icp.query_timeout INT 2
in records.config

/sbin/ifconfig -a
