Re: QZTCJK.SRVPGM, Tomcat and Apache

I put DEBUG on the JkLogLevel directive and ran both the broken and working
system.  By the results of this log, I see that my failing system is
failing at the wc_open function.  If I could understand what this function
does, I may be able to fix the problem.
NETSTAT on the 400s seems to show that all necessary ports are open on all 
systems.

I have three AS400 systems that are all the same (as far As I can
tell, PTF's, System Values, etc). All three are used exclusively for
web serving using Apache and Tomcat.

Server A and B work great, hosting up dynamic content through Tomcat
with no problem (using Struts). However, server C is not functioning.

All three servers have the exact same Apache configuration except for
the LISTEN directive. On all three the Tomcat runs great in
standalone and APache runs great in standalone. To make Apache serve
up Tomcat content I add the following commands to the apache config:

LoadModule jk_module /QSYS.LIB/QHTTPSVR.LIB/QZTCJK.SRVPGM
JkWorkersFile
/home/tomcat/jakarta-tomcat-4.1.12/conf/workers.properties
JkLogFile /www/testing/logs/jk.log
JkLogLevel error
JkMount /testing/* ajp13

When these lines are added to A and B, everything works great. When
added to C, the apache instance dumps on startup. The dump is listed
at the end for those who want to see.

I have looked everywhere I can think of. PTFs, Object Authorities,
System Values, workers.properties files,Object descriptions on QZTCJK
are the same, etc and can not figure out why this thing is dumping.

Any ideas??? I am pulling my hair out.
