[jira] [Commented] (ARIA-185) NullPool logging messages appear during execution

["Ran Ziv (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARIA-185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16022978#comment-16022978 ] 

Ran Ziv commented on ARIA-185:
------------------------------

Looks like the problem was caused by SQLAlchemy sessions that weren't closed properly.
This led to further investigation which results in the removal of the {{tracked changes}} mechanism for runtime-properties, and actually simplified much of that part of the code.
