Hi,
I'm working on creating a pair of Apache mod_jk load balancers for an Tomcat
web-app farm.
Redhat ES4
Server Version: Apache/2.0.52 (Red Hat)
JK Version: mod_jk/1.2.20
apache-tomcat-5.5.20-1
Everything works fine, until I exceed 15 load balancing workers on mod_jk, then I get a 500-Internal
Server Error, for every web-app.
Note that the 16th worker config works fine, if specified as part of the 15.
Error messages aren't much help, but are included below.
I've tried doubling all the MPM worker values in httpd.conf - no effect.
Any clues to what's going wrong?
thanks
James Masson
