High memory consumption during multi month export

Summary

With the introduction of MODEUSHARV-35 counter reports, especially Title Master Reports, can become rather sizable. We've observed that monthly reports can reach a raw JSON data size up to 50MB.

When generating aggregated reports that span multiple months, it's possible that the default memory settings are not sufficient to handle these reports. As a result, the module shuts down with java.lang.OutOfMemoryError: Java heap space and the UI displays an error message that is depicted in the attached image.

Workarounds

• Increase memory allocation for module mod-erm-usage

• Reduce report range
