title: java.lang.OutOfMemoryError: requested 32756 bytes for ChunkPool::allocate. Out of swap space?
body: <p>I am working with a java application deployed on an HP server via WebLogic 10.3. </p>
  
  <p>Version info:</p>
  
  <pre><code>WebLogic Version 10.3
  OS Version B.11.23
  
  $ java -version
  java version "1.6.0.03"
  Java(TM) SE Runtime Environment (build 1.6.0.03-jinteg_05_feb_2009_11_19-b00)

  </code></pre>
  
  <p>I am getting this java.lang.OutOfMemoryError and the weblogic managed server is shutting down. It's always on the compiler thread. The error message says to check swap and MAXDSIZ. I looked at both and they seemed ok (see below.) I've gone through the forums and looked at various things but none seem to fully apply. I've changed the heap and stack both up and down with no luck. Also, I am pretty sure this is the first 1.6 port of the application on HP.</p>

  <p>I get a core and a hs.log file. This question seems similar but not sire of the resolution.</p>

  <p>I am posting the log file. None of the Heap spaces show near 100%. I am not used to looking at these and was hoping someone could help guide me to a solution. I see physical memory goes low but not 100%.</p>

  # An unexpected error has been detected by Java Runtime Environment:

  Possible causes:
  - not enough swap space left, or
  - kernel parameter MAXDSIZ is very small.
