Problem
A client had problems with some workflow instances. Most instances did complete without a problem others failed. Especially workflow that continued after a few days reported the following error in the workflow history log:
“{Microsoft.SharePoint.SPException: The context has expired and can no longer be used. (Exception from HRESULT: 0x80090317) ---> System.Runtime.InteropServices.COMException (0x80090317): The context has expired and can no longer be used. (Exception from HRESULT: 0x80090317)
at Microsoft.SharePoint.Library.SPRequestInternalClass.SetHttpParameters(String bstrHttpMethod, String “
I did some googling and found some hits that found a solution in synchronizing the date/time of the WFE’s and admin servers. In our case that wasn’t the the case.
Cause
After digging into the problem I noticed particular workflow activity opened a site collection using an SPUserToken.
using (SPSite site = new SPSite(WorkflowProperties.SiteId, InitializationData.UserToken))
{
//do some work
}
The SPUserToken was part of the workflow context and was populated when the workflow instance was first created. Default the SPUserToken is valid for 1440 minutes (1 day). In case the workflow instance is de-hydrated after more than 1 day the SPUserToken is expired and isn’t valid anymore. You will get the message “The context has expired and can no longer be used. (Exception from HRESULT: 0x80090317” and are not allowed to open the sitecollection.
Conclusion
So when you get this specific error make sure to check if you use an old SPUserToken! And be aware the the SPUserToken can expire.

We have exact same issue where we need to kickoff workflow for readonly users with some other user's token which is getting expired as the fake user never logs in. Can we increase timeout of spusertoken to 6 months for specific user?
ReplyDeleteTokenTimeout is per WebApplication, so you cannot set this for a specific user.
ReplyDeleteA solution might be that the workflow impersonates a specific 'read-only' SPUser that does exists (that you created by deployment) and let the workflow do the necessary actions.
