Hello,I will have a look at 7u40 and 8 as soon as I get some time. But I dont think it is thread(caching) related as it does not show up in the heapdump (and we have a controled thread creation rate). It looks more like some close/cancel interactions (and a real leak).
I will let you know what I find. Thanks David, Alan and Sean! Greetings Bernd
