Connection Reset
Here is our architecture.
5 web servers (web1 - web5) and 4 java servers (java4-java7)
Each Webserver is using the same version of mod_jk (version 1.2.5) and
apache (1.3.27). Each java server is running the same version of tomcat
(3.3.1a). Red Hat is being used on both web servers and java servers.
When we have mod_jk load balancing turned on (see config at url below) the
following errors (see http://titan.cbc.ca/~bcrosby/tomcat.txt) in tomcat.err
are present.
On the webserver, the mod_jk error file shows:
[Tue Dec 16 18:18:27 2003] [jk_ajp_common.c (1303)]: ERROR: Client
connection aborted or network problems
Turning mod_jk load balancing off fixes this problem.
A copy of the workers.properties file is available at
http://titan.cbc.ca/~bcrosby/workers.txt.
Questions:
1. What is the definition of "client" according to mod_jk. In the error
message from mod_jk (see above) "client connection aborted" means tomcat
aborted the connection (tomcat being the client) or apache/mod_jk aborted
the connection.
2. Are there any values (like socket_keepalive) that are missing in my
workers.properties file?
Let me know if you need any more info.

"Client" means the browser. The message usually means that e.g. the user
hit the "stop" button. However, in this case it looks like a problem with
the load-balancer. At least that's what a quick look at the code suggests.

KeepAlive shouldn't matter much.
