In this case I am using Metro JAX-WS. It seems that the reponse is waiting in some buffer. Is there any way to inspect tomcat buffers? Network buffers? I am using linux. The strange thing is that with Tomcat 8.0.33 there is no problem. The same problem happens even with other servlets of different frameworks and other webapps. On 8.0.x I was using Nio connector, on 8.5 I am using Nio2. The problem is both on http and jsse https. Is any new relevant default value changed from 8.0 and 8.5? I can't find any idea on changelogs or documentation > > in the server side: Full thread dump Java HotSpot(TM) 64-Bit Server > > VM (25.92-b14 mixed mode): > > > > > > "anInnocuousThread" #861 daemon prio=5 os_prio=0 > > tid=0x00007ff23c0de800 nid=0xdb26 runnable [0x00007ff1ad379000] > > java.lang.Thread.State: RUNNABLE at > > sun.nio.ch.EPoll.epollWait(Native Method) at > > sun.nio.ch.EPollPort$EventHandlerTask.poll(EPollPort.java:194) at > > sun.nio.ch.EPollPort$EventHandlerTask.run(EPollPort.java:268) at > > java.lang.Thread.run(Thread.java:745) at > > sun.misc.InnocuousThread.run(InnocuousThread.java:74) > > > > (lots of this kind....)

I have stripped out GC threads, JMX... My application is not present in any thread but I have several clients stuck at waiting for a response.
