At what point did you run this thread dump? What was the state of your application? How many request were sent to the server? How many responded OK, how many failed? > Regards, > Julien. > > 2013-03-22 08:52:59 > Full thread dump Java HotSpot(TM) 64-Bit Server VM (23.7-b01 mixed mode): > > "Attach Listener" daemon prio=10 tid=0x00007f68e8001000 nid=0x41bd waiting > on condition [0x0000000000000000] > java.lang.Thread.State: RUNNABLE > > Locked ownable synchronizers: > - None > > "http-bio-8080-exec-10" daemon prio=10 tid=0x00007f68840a2800 nid=0x41b5 in This thread looks suspicious.
