Local fix

  • Use the -Xmx option to increase the size of the Java heap when
    running the trace formatter.
    

Problem summary

  • Problem is caused when the trace output being processed by the
    trace formatter contains trace data from a very large number of
    Java application threads.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR6
    6.0.1 SR7
    .
    The trace formatter has been improved to allow it to process
    data from a large number of Java application threads with lower
    heap usage.
    

Temporary fix
