Title: Mod_JK 1.2.39 Unable to connect to unknown host

Dear all,

I have Apache httpd 2.2.22 with mod_jk 1.2.39 to route traffic to several tomcat instances. In my jk status manager, I noticed that the Address:Port value is different with the host that I configured in my worker.properties. After httpd run for several hours, mod_jk throw below error  :

‘connect to 49.0.58.0:8017 failed (errno=55)’.  Where the host is a unknown ip to me

My question :

1.      Why the Address:Port is different with hostname?

2.      Why httpd unable to connect to my tomcat instance after several hours (when memory usage for httpd reaches 850MB)? If the host is unreachable, it should immediately throw unable to connect error instead of after several hours.

Below is the excerpt from my jk status manager screen.

Name            Type    Hostname                Address:Port            Connection Pool Timeout Connect Timeout Prepost Timeout Reply Timeout   Retries Recovery Options        Max Packet Size

mynode  ajp13   172.30.210.107  49.0.58.0:8017  0       10000                           10000                   0                       2               0                               8192   

Thanks.
