A session fails with an error like the following :
com.indy.engine.common.exceptions.EngineExceptionI: Unknown java.lang.error working with the engine, contact your supplier
at java.lang.Thread.run(Unknown Source)
Caused by: java.lang.OutOfMemoryError: Java heap space
This can happen on SqlOperation and SqlFileExport actions when loading a large amount of data, which fills up the Java Virtual Machine's memory.
Go into the process details, and look at the parameters of the action that failed - or the previous action if it is a bound action.
Reduce the "Fetch Size" (usually in the SQL action or in the Template parameters)
- A lower value will require the lowest memory but with slower performance.
- A higher value will require more memory but with better performance.
Alternatively, you can increase the Runtime's max memory (parameter STAMBIA_MAX_MEMORY in initvariables.bat).
A specific forum thread was created on this kind of error, feel free to discuss or ask help: http://stambia.org/forum/runtime-questions/25-my-process-crash-with-a-java-heap-space-error
