"Copy to file share” - network error when starting several concurrent workflow instances

Nintex workflow 2013 running on prem.

I have a list workflow in a SharePoint document library.

The workflow is triggered when an item is modified and uses the „Copy to File Share“ action to copy the file to a file share.  This works fine when starting 1-5 concurrent instances.  However, if I update properties on several (more than 5) documents at once using the quick edit view I always end up with one or more instances in error state.


The „Copy to file share“ workflow action returns error messages:



„An unexpected network error occurred.“


,or sometimes:

„Error Code: (1219) Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.“


I noticed that I do not get the network errors if I put a „Pause For..“ workflow action before the „Copy to file share“.
Pausing all instances for several minutes is not an option for my scenario.


Does anyone have an alternative solution?
