nsstats is repaired to behave gracefully, when no nssmptd log file is available, and someone clicks on SMTP sent log. The fix is in the NaviSever repository on GitHub. If you recreate the container, you get immediately the updated version
The /acs-admin/monitor page of OpenACS is fixed in CVS head and oacs-5-10 to behave gracefully, when uptime is not installed.
The configuration of system_pkgs with graphviz and procps was added to the documentation of the oacs-db-inclusive container (README file)
I have also added the graphviz package to openacs.org, now we have there the graphs in api-doc again.
I've also added a mitigation for the cache management, as indicated, both in the HEAD and the oacs-5-10 branch. So, a fresh installation of the oacs-db-inclusive container (or an update-from-repo tomorrow, once the .apms for oacs-5-10 are rebuilt) will be able to flush the caches via /acs-admin/cache
