in contrary to Lightroom 5.7 I noticed that Lightroom 6.0.1 stops randomly during export service of files with the message 'file could not be opened'. By the way the files which are mentioned could always be opened and accessed, so it's a false error message. I'm using Windows 7 SP1 64 Bit with 8 GB RAM and 500 GB HDD. The number of files during export could be in my case in the range of 300 new files with 12 - 36 MP. Could it be right that file handles are leaked? With export service I mean the publishing service to HDD.
Could you please fix this problem a.s.a.p. since an unsuperviced export is not possible.
