Hey,
I'm using Nintex Workflow 3.0.7.0 with Sharepoint SP1 (the correct one)
I have workflow that has a switch action.
One of the branches create a task and does a couple of webrequest there after the workflow should be ended with end workflow action.
For Nintex the workflow has a completed state but for SharePoint the status is still In Progress.
I did notice that in the same milisecond 2 connections were opened to the Nintex SQLDatabase.
When I turn on the verbose logging for the Nintex product I found following errors.
Any ideas in how this can be solved?
