APAR status

  • Closed as program error.

Error description

  • The Java heap uses significantly more memory in Business
Automation Workflow and IBM Business Process Manager (BPM)
V8.5.6 or later versions. If you are analyzing your heapdumps,
you might notice that the caches double in size. The size
increases even if no new objects are added to the system. The
branch cache often has the most noticeable change.

When reviewing the difference in memory usage with an earlier
version, you notice that most of the extra memory usage is in
com.lombardisoftware.core.TWUUID objects.
