Error description

• DETAIL OF PROBLEM:
  After upgrade of TPC or Spectrum Control to version 5.2.10
  customer
  may observe slow running probe and other jobs.  In some cases
  the
  jobs may run for a significantly longer time than prior to the
  upgrade.  The LogTraceHelpers may eventually cause an
  OutOfMemory
  condition.
  Rebooting the server will temporarily improve job run times, but
  over time run times may increase.
  RECREATE STEPS:
  Upgrade an existing TPC or Spectrum Control environment actively
  monitoring SVC/Storwize devices to Spectrum Control v5.2.10.
  Allow scheduled jobs to run and observe extended run time of the
  jobs.
