Hello Mark,
We changed the config like it was suggested on Tomcat Site, but sometimes, the
Websites takes too long and endless loading process in the frontend. But this
only for one off the apps,.. die other wepapps going on in the Cluster.
No Timeout will be thrown. In Backend everything seems to be ok.

I doubt you have that many AJP threads available on Tomcat.
AJP connector config in server.xml?
mod_jk config in httpd.conf?
Looks like my guess was right.
