Hi kaustubh,
I have faced similar errors on different scenario, the cause of the issue is the Java heap size might be insufficient for your application's needs, especially when handling larger files. I would suggest increase the JVM heap size in your Mendix runtime if it's in local.... If you facing same error in Environment you have to increase the application memory.
