Memory Leak #4

Open KevinColemanInc opened 11 years ago

KevinColemanInc commented 11 years ago

We found a memory leak with RJB. We think the ruby can't do garbage collection on objects in lines 26-28 in https://github.com/paulschreiber/pdf-merger/blob/master/lib/pdf/merger/rjb.rb because the JVM is outside of ruby's domain.

If you need to process a large number of pdfs, you may need to restart your program a few times.

Is there anything I can do to work around this? Have you filed a bug against rjb?

KevinColemanInc commented 11 years ago

I am not really sure... From what I have read, RJB inherently has issues with memory leaks.

I haven't tested this yet, but I think that Prawn can do pdf merges by setting the template of a page to a pdf file.
