Andre Zelenkovas [http://community.jboss.org/people/jbonham100] created the discussion "Crazy performance issue with JBossWS" To view the discussion, visit: http://community.jboss.org/message/561625#561625 -------------------------------------------------------------- Hi all I have a bottom-up JAX-WS web service deployed in JBoss. I was running some performance tests at different volumes and I ran into this issue: exactly one hour after the first request, the performance drops dramatically and garbage collection goes off the roof. I took some thread dumps and most HTTP threads are stuck trying to open a class for JBossWSEntityResolver. Our code is not even reached. Has anyone seen anything like it? Here's the thread dump for one of the threads, they look pretty much the same: "http-0.0.0.0-8080-149" daemon prio=10 tid=0x0000002b4245b000 nid=0x4e84 runnable [0x000000004958e000]    java.lang.Thread.State: RUNNABLE         at java.util.zip.ZipFile.freeEntry(Native Method)         at java.util.zip.ZipFile.access$800(ZipFile.java:29)         at java.util.zip.ZipFile$2.nextElement(ZipFile.java:330)         -
