Operation Instances Problems:
– Service operation instance stays in NEW status.
– Service operation instance stays in STARTED status.
– Service operation instance stays in WORKING status.

Service Operation Instance Stays in NEW Status – possible causes are:
– The domain on which a pub/sub server resides is Inactive.
– The Application server is down.
– Pub/sub services are not configured on the Application Server domain. Check the server status via Psadmin to make sure PUBSUB services are running.
– The Message Dispatcher crashed or was brought down.
– The item is not at the top of the queue; all service operations with the same queue or subqueue are in the same queue.
– The node status is in Paused state.
– Missing data from PSIBPROFILE (Document:1108466.1E-IB:Messages Stuck In New After Tools 8.50 Upgrade)
– PUBSUB processes in-memory queues got out of sync with the database because of running a purging script without shutting down the app server domain ()
– Only one domain is configured for PUBSUB services but in the psappsrv.cfg file it is set as a slave domain. The Slave Mode should be set to 0 if not implementing static master/slave.
– In PT 8.51+ the domain status page shows one active domain and the Slave indicator is Sync Template. There needs to be a master domain. Recreate the domain in PSAdmin.

Service Operation Instance Stays in STARTED Status – possible causes are:
– All Message Handlers crashed or were brought down; processing will resume when Message Handlers come back up.
– The Message dispatcher processing the message is on another machine, and either the machine or the application server domain is down.
– Application server domain was created using the developer template. Recreate using small, medium or large.

Service Operation Instance Stays in WORKING Status – possible causes are:
– Message Broker Handler crashed.
– The Message Handler processing the message is on another machine, and either the machine or the application server domain is down.
– The Message Handler working on the message is blocked. The service will time out, and the Message Dispatcher will retry the message.
– Application server domain was created using the Developer template. Recreate using small, medium or large.
