java.lang.OutOfMemoryErro

[rcjetpilot]

When using this basic command, intermittently I get the following error. Usually when I reach between 300 - 400 files or the file grows to greater than 180mb.

Also when merging files I see that it randomly grabs files with no rhyme or reason from the directory. It there a way to sort the merge without using cfdirectory and looping through the files?

HERE's the code I'm having issues with:
<CFPDF action="merge" directory="c:\backoffice\print\1" destination="c:\backoffice\send\print\1.pdf">

HERE's the ERROR Ireceive randomly:

500
ROOT CAUSE:
java.lang.OutOfMemoryError: GC overhead limit exceeded

For the error: try adding -XX:-UseGCOverheadLimit in jvm options, restart the server and run your code. It should fix your problem.

As for ordering your merge, you can use
<CFPDF action="merge" directory="c:\backoffice\print\1" destination="c:\backoffice\send\print\1.pdf" order="name" ascending="false" >

order can be name or time. By default AFAIK it should be order by name in descending order, but i may be wrong.
