Failed to publish workflow that contains User Defined Action (UDA)

When publishing a workflow that contains User Defined Action (UDA), the following error might occur:

soap:ServerServer was unable to process request. --> Failed to publish workflow: Error in the application.

Increased the UserDefinedWorkflowMaximumComplexity using the following PowerShell script:

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")

$new_limit = 50000;

$webapp = [Microsoft.SharePoint.Administration.SPWebApplication]::Lookup('webApplicationURL)

$webapp.UserDefinedWorkflowMaximumComplexity = $new_limit

$webapp.Update()

Workflow library failed to compile because it exceeded UserDefinedWorkflowMaximumComplexity of 7000
