I am not sure I understand, "my classes" i.e. stuff I created under com.knovel.* take up almost nothing of the heap, I have the view sorted by size in memory and they are way down there. Most of the heap is taken up by char[]. Byte[], String, Object[], int[] and StringBuffer. The biggest class I have is taking 100k - it never grows, it is created in a singleton at startup and is only read from, I checked it is always at 100k - never growing bigger (as expected).

This will show you which classes are taking up the most memory and if you have a leak you might expect this accumulated value to be a high percentage of the overall heap being used.. look for a percetage of memory used. -----Original Message----- From: Chanan Braunstein [mailto:[EMAIL PROTECTED] Sent: 15 April 2004 15:27 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.
