I think I've seen back posts indicating that the JMX option will do this, try removing.. <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" debug="0"/> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" debug="0"/>
>From your server.xml, we have no apparent memory leaks using the same configuration. -----Original Message----- From: Chanan Braunstein [mailto:[EMAIL PROTECTED] Sent: Thursday, April 15, 2004 10:27 AM To: 'Tomcat Users List' Subject: Memory Leak Hello, I am having a problem with Tomcat 5.0.19 on windows with JDK 1.4.2_02. The memory that java.exe is using keeps growing till the point that tomcat stops responding. Using a profiler, doesn't seem to give me any clues. I can see the memory being used by certain classes go up (mainly char[]) and even reach all the way to the point that used java heap equals to the java heap, but then GC kicks in and drops down back to where it was when I started the test. However, the memory in the task manager keeps going up. For example right now it is at 717,000 K, even though the heap used is at about 200,000 K. What am I missing here? My current params are -server -Xrs -Xms356M -Xmx356M - I tried all kinds of different sizes for the memory but that doesn't really help. Any suggestions as to where (how) to look to find my memory leak? Chanan Braunstein Knovel Corp.
