    Description

      After OpenNMS being hit with a high volume of traps, the JVM crashed with:

      # Native memory allocation (mmap) failed to map 12288 bytes for committing reserved memory.
      

      Analysis of the stack trace show a large number of threads (~32000) with this pattern:

        0x00007f47ac7fe800 JavaThread "Thread-63085" daemon [_thread_blocked, id=97856, stack(0x00007f476b8fd000,0x00007f476b9fe000)]
      

      The problem has not reoccurred since disabling trapd.
