> Key: PDFBOX-4601
> URL: https://issues.apache.org/jira/browse/PDFBOX-4601
> Project: PDFBox
> Issue Type: Bug

> in AWS lambda pdf merge giving error as
> {{Error in pdf consolidation: Expected scratch file size of 196608 but found 192512.}}
> *Code:*
> {code}
> PDFMergerUtility pdfMerger = new PDFMergerUtility();
> pdfMerger.addSources(sources);
> pdfMerger.setDestinationStream(mergedPDFOutputStream);
> pdfMerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());
> {code}
> both InputStream and OutputStream are ByteArrayInputStream and ByteArrayOutputStream. AWS Lambda environment has 512MB space available only for /tmp partition. This could be an issue or not I am not sure. And AWS lambda do not permit other directory than /tmp partition to create files.
> And while reading into the code I found below piece of code which I think always be true. Because if you add some constant amount to an integer that will always be constant amount greater than its original value
> in ScratchFile.java => enlarge() method:
> {code}
> if (pageCount + ENLARGE_PAGE_COUNT > pageCount)
> {
> fileLen += ENLARGE_PAGE_COUNT * PAGE_SIZE;
> raf.setLength(fileLen);
> freePages.set(pageCount, pageCount + ENLARGE_PAGE_COUNT);
> }
> {code}
