Hi Steve,

I noticed that you already restart SharePoint server (do you have only one server in your SharePoint Farm?).

Re: State machine stuck in change state

That is strange Steve. Pierre does provide a great tip on restarting the service and leads into another possible issue. He asks if you have multiple servers, such as a WFE and App server separate because sometimes the App servers are setup incorrectly with the services that can also cause this issue. But if you only have one server and a sql server, then this should not be affecting you.

How many workflows do you have in your farm? Do you have any others that use Pause actions? We try to trouble shoot with similar actions to try to find a common cause in the environment as they can always be vastly different. With workflows that have pause actions, if you set it to pause for 30 minutes, does it start up again without trouble? Also, what is your sharepoint version and also nintex biuld number?

Re: State machine stuck in change state

Hi Andrew

I've 7 workflows in the farm. Last night I've updated the Nintex workflow to 3.1.7 and also the SharePoint 2013 Latest CU. regarding restart the SP Timer, it only affected the new instance? Found the previous workflow instances still stuck.

I've a calute date loop which also stuck, no other pause action.

Thanks

Re: State machine stuck in change state

Update:

Restart SP timer service might be a temp solution. But if there is one action stuck then the comming up workflow will all be stacked which inculde the'state machine' unless I retart the SP timer service again. But still not found which cause this stcuk happen.

Restart SP timer service also will not resolve the previsous workflow which stuck in 'chang state'. Is there any other solution for this issue? Sometmes End use won't re start the whole workflow when the flow approval cost many days.

Re: State machine stuck in change state

I know this thread is very old, but we recently had a similar issue and the way we got ours fixed was by clearing up the orphaned workflow instances by running NWAdmin.exe -o SyncTerminatedWorkflows -url teamsiteurl -terminateDeletedItems

Re: State machine stuck in change state

From what I can remember before we went to Online is that we used "Wait" actions before switching to a next state.

My feel (theory) in that time was that with multiple WFE's it could be that the nodes were not in sync, by having that wait statement in place or by adding extra commits that was enforced. Give it a try at least.

It was a personal observation which helped me in that time.

Re: State machine stuck in change state

Jaap Steenis, So are you suggesting to remove the "Waits" and the "Commit pending changes" actions? I also noticed some workflows fail not at the change state, but also at the simple "Commit" with an error that it couldn't update item for possibly the field needs a different type of information. In some days it works and some don't and the updating of a field with the provided data type is not the problem for sure - Sharepoint error messages are always misleading.
