PI93881: SPORADIC ERROR 6 INVALID MAP HANDLE ERROR - MEMORY ALLOCATION FAILURE FUNC:RUNMERCMAP CHECKMMH FAILED MMH=FFFFFFFFF4C68060

APAR status

• Closed as program error.

Error description

• The following error condition occurs for Transformation Extender
  (TX) 64bit system on Windows if malloc returns for map handle
  address that is over 4GB.  This will likely appear as an
  intermittent issue because TX usually caches maps and allocates
  them relatively early while the process space is still small.
