Lightroom: Panorma merge reports read-only access images and fails

All my photos are located on my NAS. I only keep the smart previews on my MacBook. This is usually working pretty good. However when I am trying to merge some DNGs by means of the new panorama feature, the to-be-merged pictures are randomly reported as having read-only access which is absolutely not the case. The merge consequently fails.
My local network is stable and the drives are correctly map. It seems to be a latency issue. Possibly accessing the file attributes on the network drive takes too long...

What network file protocol does your NAS use? SMB? AFP?

Apparently OS X 10.11 uses Samba (3) as the default protocol. The shares are mounted as smb://... The NAS also supports AFP. I will check this evening if AFP makes a difference.

Unfortunately the same issue applies to AFP mounted shares. Most of the time a dialog mentioning the read-only access is popping up. Sometimes the merge window opens but it seems as if only half of the images were taken into account.

And just to confirm, you do not have this issue if the images are on the local drive?

Good question. I had not tried it before. There are no read-only-access messages. However it never merges all the images!?

The panorama consists of nine Olympus E-M1 RAW photos imported as DNGs.

If I select all of them only the last six are merged. When selecting the first five then only the first three are merged!? Merging the same photos (local HDD and network share) via "Edit In > Merge to Panorama in Photoshop..." works flawlessly.
