Information in this document applies to any platform.
You have a composite that receives XML document over a File/FTP adapter. The XML document consists of one item with multiple style elements, and each of these style elements in turn can have multiple style elements themselves. After receiving a document, a 1-1 transformation is performed within a FOR loop. When the document size is 3 MB+ the transformation fails. But if the document size is just 2.8 MB, it is successfully transformed. There is sufficient heap space on each managed server.
The issue can be reproduced at will with the following steps:
1. Receive large XML document file via adapter.
2. Exception occurs.
