There is the JVM -XX:SoftRefLRUPolicyMSPerMB=n option, where n is defined as "Number of milliseconds per MB of free space in the heap". This is used to calculate the maximum time to leave a softly reachable object around. If you set it to zero, the SSLSessionId cache should disappear pretty quickly if you force a major GC every now and then. (The default value is 1000). > > Try an allocation of a gigantic array to force > > SoftReferences to be discarded, then clear the > > reference to the array, and force another GC. > > Ugly, and it probably has really nasty side > > effects. > > This is creative but extremely dangerous since I don't know how much > real free memory I have. Doesn't matter - the goal is to force an allocation failure thereby causing a major GC that also processes SoftReference objects. A normal System.gc() call won't do that, since there's no allocation failure involved. The second major GC is required to ensure the SoftReference referents are actually released (not sure if that's still needed with the current GC algorithms). > > Submit an enhancement request, preferably with a patch for new > > attributes on the <Contector> elements to control the behavior. > > How do I do that? http://tomcat.apache.org/bugreport.html > I have a feeling they are keeping the SoftReferences even > after their default time has elapsed I suspect the default time limit for SSLSession cache, like the default space limit, is infinite. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
