opengrok docker exit with 0 abruptly

[hariprak]

Hi,
I have a source code repo which is indexed via a docker based opengrok. Since past few days, am seeing a strange problem wherein the docker opengrok exits with value 0 as follows:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5026de7693ef opengrok/docker:latest "/scripts/start.py" 2 hours ago Exited (0) About an hour ago opengrok-app

Log shows as follows:
30-Sep-2021 03:19:09.096 INFO [ForkJoinPool.commonPool-worker-59] org.opengrok.suggest.Suggester.shutdownAndAwaitTermination Suggesters for [MYREPO] were successfully rebuilt (took 0 seconds)

Waiting for reindex to be triggered

Request your help to resolve this issue.

Seems like a duplicate of #3650 , please reopen if it's not the case.

Could you pinpoint the change? New OpenGrok version or maybe a specific change in the repository?
