Java java.lang.OutOfMemoryError "Out of swap space?"

Solution Verified - Updated -


  • After running an application for about a week, the following error appears in the JBoss EAP server log:
    Exception java.lang.OutOfMemoryError: requested 32756 bytes for ChunkPool::allocate. Out of swap space?
  • JBoss crashes with the JVM creating a fatal error log with the following header and current thread information:
    # An unexpected error has been detected by Java Runtime Environment:
    # java.lang.OutOfMemoryError: requested 270480 bytes for Chunk::new. Out of swap space?
    #  Internal Error (allocation.cpp:218), pid=6932, tid=8336
    #  Error: Chunk::new
    # Java VM: Java HotSpot(TM) Server VM (11.0-b15 mixed mode windows-x86)

  • The fatal error log suspiciously shows plenty of available physical memory and swap space:
