    Description

      We're seeing undertow slowly continuing a memory consumption until we run out of heap space and start getting outofmemory errors. On analysis of the heapdump, the main suspect appears to be:

      One instance of "io.undertow.server.protocol.http.HttpOpenListener" loaded by "sun.misc.Launcher$AppClassLoader @ 0xc0041e40" occupies 967,912,832 (95.19%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentHashMap$Node[]" loaded by "<system class loader>".

      This happened immediately when moving from 1.4.22.Final to 2.0.16.Final. I suspect its being triggered by a poorly designed health check.
