For the error "... [Wed Apr 30 11:56:08 2008][3345:3086427840] [error] init_jk::mod_jk.c (2781): Initializing shm:/usr/local/apache2/run/jk.shm.3345 errno=2. Load balancing workers will not function properly. ..." check if you have " /usr/local/apache2/run " folder. Possiblity is it doesn't exist by default. The jk.shm is a temporary file created by Apache to write the shared memory data while serving requests. If the "run" folder doesn't exist, create one and see if that fixes the error. -Sudheer Ch Praveena wrote: > > Hi all ., > > I want to cluster Jboss by using apache server(httpd 2.0.63 ) > as load balancer.
