Symptoms

Enterprise Data Quality (EDQ) is installed on a system with a large number of CPU Cores assigned to the region where the application is installed. When running a Process or Job the system will become slow and may stop responding including an inability to access the User Interface.

In the EDQ main0.log file there may be messages indicating failures in communicating with the Database used by the Processes running.

Example:

[EDQ-01800] Error in database operation: IO Error: Broken pipe (Write failed)

Changes

This is more likely to occur in a new installation.
