SharePoint workflow timer job is stuck at "Pausing"
In SharePoint Central Administration, a workflow timer job shows the status as "Pausing." As a result, you experience the following issues:
- Approvals of tasks don't complete.
- Workflows can't run after a pause.
- Random processing of workflows occurs.
- Workflows don't function over extended periods of time.
The most likely cause is a bad workflow instance.
To fix the issue, first determine whether it's caused by a workflow definition that was introduced in the system or by a bad workflow instance. After you verify that, work with the workflow owner to decide whether the workflow can be terminated or deleted.
Step 1: Restrict servers that run the workflow timer job (optional but highly recommended)
To diagnose the issue quickly, consider stopping the Microsoft SharePoint Foundation Workflow Timer Service on all servers except one.
Step 2: Set ULS logging level to VerboseEx
In the SharePoint Management shell, run the following command:
Set-SPLogLevel -TraceSeverity VerboseEx
Note This may cause performance issues on the farm. We recommend that you restrict the duration to the minimum and reset the ULS logging level to the default value after the behavior has been reproduced by using Clear-SPLogLevel.
If the performance impact prevents full VerboseEx tracing, set the logging level for all categories to Verbose and the logging level for "Legacy Workflow Infrastructure" (or "Workflow Infrastructure" in SharePoint 2010) and "Timer" categories to VerboseEx. To do this, run the following commands in the SharePoint Management shell:
Set-SPLogLevel -TraceSeverity Verbose Set-SPLogLevel -TraceSeverity VerboseEx -Identity "Legacy Workflow Infrastructure" Set-SPLogLevel -TraceSeverity VerboseEx -Identity "Timer"
Step 3: Clear configuration cache
Clear the configuration cache on all servers where the workflow timer job is stuck and on the servers where Microsoft SharePoint Foundation Workflow Timer Service is started.
Step 4: Wait until the issue occurs again and collect ULS logs
After the configuration cache is cleared, the status of workflow timer job will change from "Pausing" to "Paused" and then "Running." Wait until the issue occurs—it usually takes ten minutes. You may also see that the workflow timer job starts on another server if the job can run on that server.
Check the ULS logs every five minutes to see whether the issue was reproduced, and the timer job is stuck. The issue is displayed in the ULS logs before the timer job status becomes "Pausing." If no new entries for the "Timer Job job-workflow" are created In ULS logs, the timer job is stuck. When this occurs, filter the ULS logs by using the following condition and check the time of the last entry:
Name Contains Timer Job job-workflow
Step 5: Examine ULS logs
Open ULS logs in ULS Viewer, and then apply the following filters:
Name Contains job-workflow EventID Contains ahk8y
Find the last workflow that was being processed. Mostly likely, this is the workflow instance that caused the issue. Here is an example:
SharePoint Foundation Legacy Workflow Infrastructure ahk8y Verbose In RunWorkflowElev(), begin processing events for instance: bb7e3f4f-74ac-43f7-a31e-faa7e900843e 8329f59d-0342-20c3-fa1a-56f9161ded9f
Clear all filters, and then apply the following filter:
Correlation Equals <Correlation_ID> And
Message Contains proc_GetWorkflowAssociations And
[EventID Contains b6p4 Or
EventID Contains tzkv ]
In the example, the Correlation ID is 8329f59d-0342-20c3-fa1a-56f9161ded9f.
Locate the last occurrences of events b6p4 and tzkv, and then find the ListId, SiteId, ItemId and WebId. Here is an example:
05/25/2017 12:28:43.27 OWSTIMER.EXE (0x9318) 0x6DF0 SharePoint Foundation Database b6p4 VerboseEx SqlCommand: ; EXEC proc_getworkflowassociations '8dd5c889-47a6-4798-93ef-8652609278f4', 'j3952987-5ca6-4eae-8530-13e83acf1bb0', 'e22969ea-f883-4e99-8cbd-4b799a884d2d', 'm82r99b0-ff01-4448-9907-e2cbbbca0586', @contenttypeid, @RequestGuid OUTPUT 8329f59d-0342-20c3-fa1a-56f9161ded9f 05/25/2017 12:28:43.27 OWSTIMER.EXE (0x9318) 0x6DF0 SharePoint Foundation Database tzkv Verbose SqlCommand: 'proc_GetWorkflowAssociations' CommandType: StoredProcedure CommandTimeout: 0 Parameter: '@RETURN_VALUE' Type: Int Size: 0 Direction: ReturnValue Value: Parameter: '@SiteId' Type: UniqueIdentifier Size: 0 Direction: Input Value: '8dd5c889-47a6-4798-93ef-8652609278f4' Parameter: '@WebId' Type: UniqueIdentifier Size: 0 Direction: Input Value: 'j3952987-5ca6-4eae-8530-13e83acf1bb0' Parameter: '@Id' Type: UniqueIdentifier Size: 0 Direction: Input Value: 'e22969ea-f883-4e99-8cbd-4b799a884d2d' Parameter: '@ListId' Type: UniqueIdentifier Size: 0 Direction: Input Value: 'm82r99b0-ff01-4448-9907-e2cbbbca0586' Parameter: '@ContentTypeId' Type: VarBinary Size: 512 Direction: Input Value: Parameter: '@RequestGuid' Type: UniqueIdentifier Size: 0 Direction: Input Value: '8329f59d-0342-20c3-fa1a-56f9161ded9f' 8329f59d-0342-20c3-fa1a-56f9161ded9f
In the example, the ListId is m82r99b0-ff01-4448-9907-e2cbbbca0586, the SiteId is 8dd5c889-47a6-4798-93ef-8652609278f4, the ItemId is e22969ea-f883-4e99-8cbd-4b799a884d2d, and the WebId is j3952987-5ca6-4eae-8530-13e83acf1bb0.
Step 6: Identify the workflow
In the SharePoint Management shell, run the following commands to find the web URL and the list title:
$web= (Get-SPSite -Identity <SiteId> |Get-SPWeb -Identity <WebId>) $list = $web.Lists.GetList("<ListId>", $true) $list.ParentWeb $list.Title
Note SiteId, WebId, and ListId are placeholders for the SiteId, WebId, and ListId that were found in Step 5.
Go to the list and find the item by using ItemId. You can also create a temporary view on the list and filter it by ITEMID. The problematic workflow is associated with the item. Go to the workflow setting of the item. If the item has multiple workflows running on it, click the status column of the problematic workflow to view the workflow history page.
Step 7: Terminate the workflow
Examine the workflow history to identify what is wrong. Then you can terminate the workflow or delete the item.
Sometimes you may not identify the workflow or item in Step 6. In such cases, make sure that you are viewing the correct list and inspect all other pieces of data. Also check recycle bins.
If you still can't find the item or workflow, it is possible that the item was deleted but the workflow instance is still running. In this case, run the following commands in SharePoint Management Shell to cancel the workflow:
$web = Get-SPWeb <WebURL>
#Pass the workflow Instance Id from the ahk8y event $WorkflowInstanceID = <WorkflowInstanceID> $workflowId = [GUID]$WorkflowInstanceID $workflow = New-Object Microsoft.SharePoint.Workflow.SPWorkflow($web, $workflowId); [Microsoft.SharePoint.Workflow.SPWorkflowManager]::CancelWorkflow($workflow)
