IT17542: MEMORY GROWTH CAN OCCUR OVER TIME IF THIRD PARTY POOLING SOFTWARE LEAVES ORPHANED OR UNMANAGED IDLE CONNECTIONS

APAR status

• Closed as fixed if next.

Error description

• Incoming pooled connections to the jsonListener accumulate
  events to be processed. If the incoming connection is not active
  the connection becomes idle and the events will build up causing
  Memory Growth. To workaround the problem you can set a
  listener.idle.timeout to a millisecond value greater than zero.
  This will instruct the jsonListener to remove these idle
  connections and ensure the Memory Growth does not occur.
  

Local fix

• Set jsonListener configuration setting listener.idle.timeout
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Customers using the listener with listener.idle.timeout=0    *

  * PROBLEM DESCRIPTION:                                         *
  * See Error Description                                        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Workaround is to set listener.idle.timeout to a non zero     *
  * value, for example listener.idle.timeout=300000 (value is    *
  * specified in milliseconds).                                  *
  *                                                              *
  * Otherwise upgrade to listener packaged with 12.10.xC8 when   *
  * release is made available.                                   *
