CLP-package: search scheduler generating weird error logs

[haiqi96]

Bug

In the latest CLP package, the search scheduler container keeps prining out the following error log:

Traceback (most recent call last):
  File "/opt/clp/lib/python3/site-packages/sqlalchemy/pool/base.py", line 374, in _close_connection

During handling of the above exception, another exception occurred:

It is not causing any functional issue in the scheduler yet, but it could be worthwhile to take a look.
