Issue/Introduction

If you recently upgraded your Network Flow Analysis to 24.3.10, you may run into an issue where the data stops processing immediately after:

"Max Buffer Used Percent" in the harvester-wrapper.log is showing over 90%, deleting .NTA files do not help. 

These symptoms may also be accompanied by high memory usage by one of the java.exe processes.

 

Environment

Cause

This is due to a bug in our Harvester code that was introduced in Network Flow Analysis 24.3.10.
