    There is a "null" at the end of each SystemErr line,in the
    log, when HPEL is enabled. The issue only happens when there
    are SystemErr records logged, where the following stack trace
    also have a "null" appended at the end, with HPEL enabled. An
    example of this issue can be seen below, in a snippet of the
    SystemErr log records:

Problem conclusion

  • The issue was resolved by adding logic to check for null,before
    appending the data to the buffer. This ensured that the "null"
    was not appended at the end of each SystemErr line, when HPEL
    is enabled.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.11 and 9.0.0.2.  Please refer to the
