Symptoms
I have a primary workflow that calls several IPC workflows. The other IPC workflows were started and ran. I have one that shows that it is Active but I cannot find the process for it. I can't find it through workspace and the viewflow shows that that the Sub-process is unavailable. I have attached the log but do not see any obvious errors. I have also attached the Activity report that shows the process is Active.
Diagnoses
We found a single entry [Server].[IPCAsync] table matching the IPC call from the [Server].[IPC] table with a Status of '1'. Here is a list of what each Type represents:
1 = IPC Start (Sync/Async)
2 = IPC Return (Sync)
3 = Fetch (Sync/Async) and transfer data to parent (Sync only)
4 = Remove IPCReturn (Sync only), Remove IPC and IPCAsync records (Sync/Async)
Resolution
After restarting the K2 blackpearl server service, the [Server].[IPCAsync] was processed and the IPC process started successfully.
