Parallel runs in SAS® Regulatory Risk Management (on SAS® 9.4) do not progress because SAS® Infrastructure for Risk Management Server runs out of JVM heap memory. The expanded heap contains 19.9 GB out of the large chunk of retained heap (16.8 GB) within the SAS Infrastructure for Risk Management Server distributed Gemfire region map.
A single-token HashMap consists of a node table, which contains increasingly pinned, very large character key-value pairs that appear to be duplicated. This causes the error to occur:
