PI88192: Map entries do not expire at the right time after an update operation.

APAR status

• Closed as program error.

Error description

  ObjectMap.setTimeToLive() with an update operation.  When this
  happens  entries stay in the grid longer than intended causing
  a memory leak.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of eXtreme Scale who use time to      *
  *                  live eviction function and use the          *
  *                  ObjectMap.setTimeToLive() API to override   *
  *                  the default time to live.  Users of         *
  *                  eXtreme Scale who use the HTTP session      *
  *                  replication function are also affected.     *
  ****************************************************************
  * PROBLEM DESCRIPTION: Map entries do not expire at the time   *
  *                      that they were configured to when the   *
  *                      timeout is overriden with an update     *
  *                      operation.                              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When processing update operations where the user overrides the
  time to live for the entry, the precision of the timeout
  value that is flowed from client to server is not correctly
  processed.  This miscalculation causes the timeout that is
  used to determine the expiration time to be larger than it is
  supposed to be.  The calculation for the expiration time was
  updated to use the right value for the timeout.
  

Problem conclusion

• An interim fix is available for this APAR on fix central for
  the 8.6.1.2 release.
