It certainly stops logging. This may be because of the requests not reaching Tomcat so its obvious it does not have to log anything or the Tomcat is Hung or Restarts due to which we see the missing logging.
Can you please suggest how can we monitor the server health to understand if the missing logging is desired or problematic ?

SYNOPSIS
glance-scrubber [options]
DESCRIPTION
glance-scrubber is an utility that cleans up images that have been deleted. The mechanics of this differ depending on the backend store and
pending_deletion options chosen.
Multiple glance-scrubbers can be run in a single deployment, but only one of them may be designated as the 'cleanup_scrubber' in the
glance-scrubber.conf file. The 'cleanup_scrubber' coordinates other glance-scrubbers by maintaining the master queue of images that need to
be removed.
The glance-scubber.conf file also specifies important configuration items such as the time between runs ('wakeup_time' in seconds), length
of time images can be pending before their deletion ('cleanup_scrubber_time' in seconds) as well as registry connectivity options.
glance-scrubber can run as a periodic job or long-running daemon.
