Stream size – PEGA0029 Alert message is not accurate



Multiple PEGA0029 alerts are generated in the Pega Platform 7.4 environment due to incorrect stream size.

For example, Stream pzOnlyOnceChanges and pyLoadingMessage

Error Messages

PEGA0029 alerts

Steps to Reproduce

Use the application for a  long period of time. PEGA0029 alerts are generated in the log.

Root Cause

UI templating generated large HTML streams which increased the number of PEGA0029 alerts.


As a local-change, increase the alert threshold to 375 * 1024.
