Steve Lawrence commented on DAFFODIL-3030:
------------------------------------------
I did some very brief profiling and saw an overwhelming number of Xerces
objects. This might be related to DAFFODIL-2901 and how the TDML runner
creating excessive validators. And maybe the changes to the validation API are
making the situation worse than it used to be?
Would it be possible to switch the project to limited validation and see if the
memory issue goes away? Maybe the expected validationErrors are similar enough
that the TDML tests do not need significant changes? If the memory goes away,
that would at least confirm if this is something related to full validation and
possiblt the TDML runner doing things inefficiently.

> I'm seeing a significant increase in memory required for a particular DFDL
> schema project (P8). Prior to 4.0.0 the test suite (running "sbt test")
> required around 10GB of heap space to complete. After 4.0.0 it needs over
> 20GB.
