IT33982: HTTPINPUT NODE'S ADDITIONAL INSTANCE THREADS ARE ALWAYS ACTIVE AND DO NOT BECOME IDLE

APAR status

• Closed as program error.

Error description

• The additional instance message flow threads are expected to
  return to the thread pool if there is not enough workload. But
  the additional instance threads created for the HTTPInput node
  will always be active and process/wait for the input messages.
  These threads are not returning to the thread pool once the
  message load is reduced which will cause
  "TimesMaximumNumberOfThreadsReached" value in the accounting and
  stats data to be incorrect.
