I have Sync 2.3.8 running on Ubuntu 16.04 LTS (64 bit), backing up files from my Android phone to an external hard drive (file system is NTFS). Only 2 directories are being synced, and there are only 500 or so files total. Sync is constantly using 25% or more of my CPU, and if I go to the gui screen both folders constantly show they are indexing. The debug logs are filling up rapidly, and there's 2.4 GB of files in the log directory. It's creating a new sync.log file every six or seven
