Emails do not get sent, autorun and other plugin jobs are not processed, workflows are stuck, and when viewing the Manage Background Jobs page the jobs are in a pending or permanent processing state.
In rare cases, a network interruption can cause a processing svservice job to fail and not complete. Svservice will not be able to move past this stuck job.
Connect to the SQL instance containing the Winshuttle Workflow database. Expand the database tables. In the svservice table, find the stuck jobs by their IDs. These jobs will be in a status of Processing. Use an UPDATE statement to set these jobs back to pending, in which case svservice will attempt to run the job again, or place it in an error status and svservice will skip over it.
1 = Pending
2 = Completed
3 = Error
4 = Processing
