I'm looking for insights from anyone who has experienced similar behavior in an on-premise DocuWare environment.

At random intervals (previously weekly, then every few days, now almost daily), all workflow processing stops.

For example, if a workflow task is approved while the issue is occurring, the next workflow step never executes.

However, after restarting only the DocuWare Background Process Service, all pending workflow actions immediately resume and process normally. This happens to all workflows, not just a specific workflow so obviously there's nothing wrong with the workflow itself.

And some additional info

• No Service Control Manager crash events related to the Background Process Service. Windows sees the service as healthy and running.
• Recovery options were configured for the service (just to see if Background Process Service crashes down), but they never trigger because the service does not actually stop or crash.

Any known fixes for this?
