Unable to upload large video file (600 MB) #341

I have a task to upload large video files for educational content distribution. I am using IBM FileNet Content Manager 5.2. I can do the task using WebDAV, it works excellent, but WebDAV is going to be deprecated in future realises of IBM FileNet, so I am looking for new solutions. I have set up IBM CMIS for FileNet and I have set up CmisSync and it works OK. The problem with large file, I use 600 MB file for testing. After start of synchronization my FileNet became unresponsive. Also I noticed that since the start of syncing of that file, FileNet started to use huge amount of memory (looks like entire file went to RAM). I guess this is the cause of my problem.
