Hi, Hmm. I commented out the shm.file line in my jk2.properties because it doesn't seem to be working, but I just did a test with it uncommented, LD still works fine. However, if I use anything other than file=anon in the workers2.properties file, I don't get the Scoreboard info on the jkstatus page, kind of strange. Yang

I note that you have the following: [shm] info=Scoreboard. Requried for reconfiguration and status with multiprocess servers. file=anon #size=104856 #debug=1 Do your tomcat servers have a corresponding entry in their jk2.properties file? Like this? channelSocket.port=8019 shm.file=/mnt/logs/jk2.shm Is this even necessary for load balancing? -Tom --- Yang Xiao <[EMAIL PROTECTED]> wrote: > Yes. > > -----Original Message----- > From: Thomas D.
