TYPO3 Core

There are different kinds of log messages created by different TYPO3 components.

The Frontend component="TYPO3.CMS.Frontend.ContentObject.Exception.ProductionExceptionHandler" writes a complete stack trace to the log.

The TYPO3.CMS.Core.Error.ProductionExceptionHandler (e.g. called in BE) does not.

This makes it difficult to troubleshoot these kinds of errors.

Example with TYPO3.CMS.Core.Error.ProductionExceptionHandler¶

(added line breaks for better reaability):
