Detected a stalled snap thread: Pipeline Execute

Team,

We are seeing this message in the Pipeline Execute Snap “Detected a stalled snap thread: Pipeline Execute”. And the child pipeline did not process any document but shows that the execution time as 14 hours and still executing. The first snap in the child pipeline is Oracle Execute Snap where we truncate the table but it did not start or finish the execution, instead it shows the execution time as 887 mins.

Can you help us to understand what this message means we see in the runtime_logs message.

Thanks,
Dhivya Aroma.
