Hangs during write: is there a limit to the # of files?

I successfully installed the NTFS driver V10.0.1 (eval mode for now) and started a copy of my iPhoto library (115 GB, ca. 50'000 files) to an external USB disk. All worked well and ran quickly (ca. 20MB/sec) until about 1/3 of the way through. Then the system just hung with the error message "Your Mac OS X startup disk has no more memory available for application memory" (see screen shot). The system disk is a 750GB drive with over 250GB free.
The system was frozen at this point, so I had to force a shutdown. Upon restart, Disk Utility found nothing wrong with the disk.
So why did this happen? Is there a limit to how many files I can copy at once? Is there a way I can get this copy done?
Thanks,
Jan
P.S. Before you ask: YES, I am using Time Machine, but it has its limits and issues, so I create occasional snapshots of my iTunes and iPhoto libraries.

 

I don't believe there is a file limit, have you attempted to move smaller amounts and does it fail? The Screenshot error you provided, does not generally reference any paragon error that I know of. I would recommend using Google or yahoo to reference that Mac based error that is occurring, it could be something having to do with Paragon, but I am unfamiliar with it. From what I read from that it sounds like too many applications are running at once. Not that you are actually out of space on the drive.

 

Hi Matt,
I just deleted my response to your questions, because after more testing, I believe the problem lies somewhere else, not with NFTS for Mac. For example, it could be an issue with corrupt directory entries on the USB disk, etc. After more tests, I found that NTFS for Mac runs really well and the problems I was seeing I reproduced when running from a Windows 7 VM on my Mac, as well.
I also successfully tested with large files (single file of about 420MB).
Thank you again for your quick response and help--I need to dig deeper but elsewhere!
Great product--I just upgraded from trial to a purchased copy!!
