Failed to commit workflow on "Commit Pending Changes"

We are currently facing an issue when we try to set item permissions (single users, SP Groups) on an item in a list with about 7500 items. This error occurs 2-3 times daily on our production System (SP2013, Nintex 2 App, 2 WFE ), on our Test System (same configuration) we don't have such errors. A specialty in our environment is our Active Directory with dozens of Trusts to other inhouse AD's.


This is an overview of the complete WF, Size 160kb:



This is the Error message from the ULS:


Nintex.Workflow.NWActionExecutionException: Failed to commit workflow.

Some hints are very much appreciated.

Re: Failed to commit workflow on "Commit Pending Changes"

The Set permissions operation is rather costly as it must recalculate all relevant ACLs in the database. If you have numerous granular permissions in this list, and on other lists and libraries in the same database, that might cause the calculation to take longer than the configured timeout allows. I'm not sure if the number of AD trusts plays a significant role here, but it might. The Log to SQL Database action set shown in the picture also could take up some of the precious time between commits.
