I'm guessing the folder contains a large amount of files?

[joshtrichards]

@AlvaroBrey Looks like 1500 files :-)

Problem still persist (version 3.27.0). Android has limit for sending data throw IPC. So app goes throw exception in file com.owncloud.android.files.services.FileUploader.uploadNewFile(FileUploader.java:974).
