CUNY Academic Commons

Previously: #6731

The broken-link-checker plugin runs a cron job on a regular basis that scans for links in post content, pings the links, and records those that 404 or time out. Unsurprisingly, this process can take a very long time. Recent debugging leads me to believe that it might be one of the culprits in our ongoing saga of open connections.

The cron job seems to be important to the way the plugin works (link rot happens over time) so I don't want to disable it completely. The plugin does have a few limiters built in for execution time and memory usage, but the limits are set too high for a site like the Commons. I'd suggest we filter them so that they can't be set over a certain amount. See https://boonesparty.commons.gc.cuny.edu/wp-admin/options-general.php?page=link-checker-settings etc.
