<div class="jive-rendered-content"><p>Hi all</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Here's the thread dump for one of the threads, they look pretty much the same:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>"http-0.0.0.0-8080-149" daemon prio=10 tid=0x0000002b4245b000 nid=0x4e84 runnable [0x000000004958e000]<br/>   java.lang.Thread.State: RUNNABLE<br/>        at java.util.zip.ZipFile.freeEntry(Native Method)<br/>        at java.util.zip.ZipFile.access$800(ZipFile.java:29)<br/>        at java.util.zip.ZipFile$2.nextElement(ZipFile.java:330)<br/>        -
