[galaxy-dev] Custom Get Data page doesn't recognize completion of large file downloads

I have a custom module/page created to get data from some SOAP-based web services. I haven't determined the threshold yet, but for small BAM files, Galaxy behaves just fine. However, when I get large BAM files (I've had the same results with 10gig and 40gig files), Galaxy doesn't recognize when the download is complete.

I can look in the /database/files/000 directory and see the download is complete (md5sum confirms it), but Galaxy just keeps on saying "Job is currently running". It takes a Galaxy reboot for it to recognize the complete download.

Any ideas on how to fix this?

Thanks
