Hello Björn, You might want to wait for 9.0.4 later to redo your test run. Or have a try with the daily stable9 build (upcoming 9.0.4): https://download.owncloud.org/community/daily/owncloud-daily-stable9.tar.bz2
It was found that for long running processes like cron jobs or OCC commands the memory wasn't properly freed between users. Or let's say things were cached and not removed from the cache when not needed any more, which leads to out of memory errors. These problems were fixed on stable9. Regarding the case about LockedException I'm not sure it's fixed, let us know if you see it happening on stable9. If they do, please raise a bug report. It is important to find out how the shares were configured for the file for which the locked exception is occurring. And about the master key mode, what Victor said is not 100% correct. In regular encryption mode every user have their own private/public key pairs, and the private key is protected by the user's password. It is more secure. However in "master key mode" there is only on key (or keypair) and all files are encrypted using the same keys. The master key mode is less secure but allows more flexibility like adding users to group for which there is already a group share, which is not possible currently in the regular mode. Hope this helps. Cheers, Vincent On 06.07.2016 23:11, Bjoern Voigt wrote: > Victor Dubiniuk wrote: >> 1.
