I would like to know how scalable is JRun4?
We have been using JRun4 for quite some time, but it suddenly behaves erratically - once the server is restarted it works normally.
We have about 9 applications (simple applications) running on the server. I wonder is this the cause of problem.
all these apps runs in 1 JVM ? well to start with ,you may need to look into vertical scalling. and divide the apps to run into different jvm's....that is ..if these apps hv low traffic and there is no load on the CPU+memory
