Not to dismiss your problem, but these kinds of things tend to be problems with the application rather than problems with Tomcat. Are you able to use a profiler that can tell you where the object allocations are actually occurring? It's not unusual to have a ton of byte[] objects, char[] objects, String objects, and Class objects. I'm guessing that the MessageBytes, ByteChunk, and CharChunk objects in your heap summary are all related to the byte[], char[], and String objects you can see there as well. Have you been able to compare the numbers of those objects after, say, 100 requests with the same object counts after, say, 10000 requests? It /is/ possible that Tomcat is leaking memory per connection, but very unlikely given that thousands of servers are humming along quite nicely without such problems. It's also possible that Axis itself is doing some type of caching or actually leaking memory somehow, but I also doubt that it does. The only really good way to figure out what's happening is to instrument your JVM and then test the hell out of it. Use JMeter to generate load (serial or concurrent) and observe the heap, etc. You might even try to disable some of the SOAP methods you are testing to see if this leak only occurs with certain calls, or combinations of calls.
