For example, take this notice (published shortly after a mariadb restart): https://gnusocial.net/notice/14505811
The notice is not federated to other servers, only published locally. Restarting queuedaemons fixes (or, to be more precise, mitigates) the issue.

ExecStartPost=/bin/sh /var/www/gnusocial/scripts/stopdaemons.sh
If you have monit installed and configured to boot queuedaemons, the previous line stops them, and monit reboots them within minutes.
