I have one executor being created at PagingManagerFactoryNIO. That executor is shared with all the PagingStores (i.e. all the addresses): Before change: | public PagingManagerFactoryNIO(final String directory) | { | this.directory = directory; | this.executor = Executors.newSingleThreadExecutor(); | } | After change: public PagingManagerFactoryNIO(final String directory) { this.directory = directory; this.executor = Executors.newCachedThreadPool(new JBMThreadFactory("JBM-depaging-threads")); } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174338#...
