We have development environments running with multiple app. servers in jboss-3.0.6_tomcat-4.1.18 and mod_jk.so on Redhat AS 2.1. If the worker.list=appsrv20,appsrv19,....,appsrv02,appsrv01's line in the workers.properties, mod_jk's configuration file, reaches the limitation of 1024 characters, the app. servers in the end of this lines which touched by this limitation will cannot work with mod_jk.
I tried to overcome this limitation in replacing the mod_jk v1.2.1 with v1.2.5 but still cannot fix this problem
