heap space issues resulting from multiple schematron files

[mmorse693]

I'm getting heap space issues from processing multiple schematron files. In my environment I process random XML/schematron file pairs, when I process a high volume of data I have heap space issues.

@mmorse693 well yes. In the background, the Schematron is converted to XSLT and the XSLT is applied to the XML which usually must be read fully into memory. So it's all about heap and CPU when using Schematron :)

so, the issue is that the JVM isn't garbage collecting memory quickly enough? It does run out of memory if the high volume continues. Is there a way to mitigate this problem?

There is a multitude of potential parameters like:

• size of the Schematron
• complexity of the Schematron
• Size of the XML to validate
• Whether you enable caching or not

How much RAM did you use? Below 4GB is not recommended....
