Unable to import large XSD files into Pega



Thread dumps appear in the logs and the import fails when importing a large XSD file (<1GB) into Pega.

Error Messages

ERROR: posted transaction id 'cb1ce043165f3594513dc7584ce170fa' for frame 'pyWorkPage' DOES NOT match record '9a9dcb943152894df45ca4e28533e94b'

Steps to Reproduce

Run the Connector and Metadata Wizard to import the XSD from a server and create data mapping rules.

Root Cause

A defect or configuration issue in the operating environment. Pega JVM was only configured to use 1GB of heap space.


Make the following change to the operating environment:

Increase heap space to at least 4GB, the minimum recommended amount of heap space. If necessary, create rules one at a time to reduce the amount of heap space used.
