Real-time indexing process has terminated unexpectedly

What causes this issue?

This message is issued if the last-executed process for ESH real-time
indexing has terminated<(>,<)> or has been terminated<(>,<)> before the
final status update. This situation is reported if the process for the
ESH real-time indexing is not running at the point of time of the check,
but the last recorded status is still wrongly indicating the process as
'running'. The reason for the process termination can no longer be
determined by the real-time indexing engine.
Possible causes:
The real-time indexing job has been cancelled manually
Work process has been terminated in SM50
Connectors have been deleted / ESH has been reset while real-time
indexing was running
System has been shut down or restarted while the real-time indexing
process was running
Real-time indexing process has terminated without being able to update
its status, for example, due to a runtime error

System Response

How to fix this error?

The real-time indexing process will automatically restart with the next
data package that arrives for indexing. If the issue was due to a
one-time incident (e.g. system shutdown, manual job cancellation) the
status will not occur the next time, and no further actions are
required. The next process execution will automatically reprocess all
entries which could not be processed because of the preceding job
termination.
If the message reoccurs each time the real-time indexing job runs (job
never completes successfully) check for object-related issues: for
example, check job logs in SM37 or check for runtime errors in ST22.
If you do not want to wait for the next auto-restart of the real-time
indexing process you can also restart the real-time indexing manually
from the ESH Administration Cockpit:
ESH Administration Cockpit: Go to System Settings and open the Real-Time
Indexing Administration.
Start the process by choosing 'Start'.
We recommend a manual restart if a lot of data to be indexed (open
change pointers) has accumulated in the real-time indexing queues.
If you do not have any search connectors which are relevant for
real-time indexing (for example because all search connectors have been
deleted in the meantime) an auto-restart will not be triggered. Also in
this case, we recommend a manual restart of the job to update to a final
status (the job will not execute anything in this case).

Procedure for System Administrators

For more information on the concrete reason of failure, check process
logs in the ESH Administartation Cockpit, refer to the system log
(SM21), or check for runtime errors (ST22).

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
