Meta Chain- Local Chain start job hangs

Gurus, I am trying to create a meta chain (MC1) to control our nightly processing. Currently, I am experimenting with a meta chain (MC1) that is executing 1 process chain (PC1). The meta chain (MC1) is scheduled by triggering an event. The local process chain (PC1) has a start condition of "Start Using Meta Chain or API".

My problem is that when I start the meta chain (MC1), I see the process for the process chain running. But the BI_PROCESS_TRIGGER job for the local process chain (PC1) is just sitting in an "active" state. It doesn't finish or trigger the next process in the process chain. Am I doing something wrong?

Much appreciate the help, and will reward.
