We upgraded from Laserfiche Avante 8.3 to Laserfiche Avante 9.1 back in March 2014.
We have a main “Vendors” folder that currently has 5,315 subfolders—one for each vendor number. Within each vendor number folder is a set of up to 6 subfolders.
All subfolders under the “Vendors” folder are inheriting rights from their parent folder with the rights originating at the “Vendors” folder.
Since we’ve upgraded to Laserfiche Avante 9.1, I have been unable to add or remove rights on the “Vendors” folder.
The three times that I have tried, the Laserfiche Client hangs and becomes unresponsive. This is then followed by the following error message.
The operation cannot complete because an object is locked. 
We checked the “Activity > Entry Locks” section in the Administration Console, but there were no locked entries.
All users who try to navigate the repository after we first get the above error message get a sluggish response that eventually leads to them getting the same error message.
We didn’t have any issues adding or removing rights in Laserfiche Avante 8.3.
The “Vendors” folder is the one folder within our repository that has such a large number of subfolders. All other folders generally have only a handful of subfolders. Adding or removing rights on other folders does not result in this error message.
Oddly enough, we were able to run Workflows on two separate occasions to remove rights from the “Vendors” folder, and the Workflows completed successfully.
The easiest way to clear up this issue has been to reboot the Laserfiche server, which clears out the “lock” and returns the repository functionality back to the way that it was before the error message.
Unfortunately, I am leery of attempting to add or remove rights from this folder again, as I’m confident that we’ll get the same error again.
Any ideas on what might be causing this issue and a possible solution? Has this been reported by any other users?
