I have reusable workflow in sharepoint 2013. It is created in SPD 2013. This workflow is designed to assign tasks to the groups and various approval levels. It seems looks like big. I have been publishing this workflow many times earlier and is working fine. Just I made some customization in my workflow last week. After that I'm unable to publish it. I'm getting the following error.
"Unexpected error on server while associating the worklow"
I increased the "UserDefinedWorkflowMaximumComplexity" of my SharePoint application. Workflow has around 20000. Also resetted the IIS. But everything has failed.
Thanks in advance.
