[jboss-user] [JBoss Cache: Core Edition] - Tuning Cache for optimum memory

[sudarshanacharya]

I am using JBoss Cache 3.1.0 "Cascabel", with a single node, with mostly default configuration but this:


        
         
         
         
        
    

    
        

            
        

      
         location=/tmp/mycache

      



This is causing a memory leak in my application, with the old generation full every few days and the full Gc doesn't collect it, leading to bigger problems.

Heap dump shows that there are millions of cached objects in memory (), and thousands of ConcurrentHashMap, Weakreference and SoftReference instances. 

This probably isn't a bug with JBoss cache. But what are the major parameters that I should tune so that don't have the memory leak.

I have done through the docs several times, but I am looking for best practices and guildelines.
