Hi,
3 machines, - pathsrv1, raid2b, reptile - Macs with OSX 10.5.6.
Apache 2.2.9 mod_jk 1.2.26 and Tomcat 6.0.18. Every machine has one
Tomcat instance and they form a cluster. Pathsrv1 act as a reverse
proxy, so the request for the only clustered web app is coming as:
http://pathsrv1.yalepath.org/apps/CassetteLabeler.
The application works fine. It seemingly also fails over. The
session is replicated. However et every startup I see this in the
catalina.<date>.log:
