Hi @csn123
The plugin might indeed be making quite a lot of requests as in order to check the links it actually has to visit/fetch them.
The more links there are the more requests have to be made and if a lot of these links are “self links” (point to the site the plugin is running on) it might be somehow “throttled” by or “heavy” for the server.
You are right about both the “Run” options. They won’t really spawn “multiple instances) but disabling them is one of the ways to limit/throttle the “intensity” of plugin requests and while it might cause the checking process to slow down (so link discovery might come “slower”) the plugin will still work anyway. These, however, are mostly about “link discovery” so you might also want to
– set shorter timeout in “Timout” option in “Advanced” settings of the plugin
– set shorter “Max execution time” on the same page as this will, again, make process slower but also make it check less links in one go, hence should limit requests
– you can try (on the same page as well) limiting Server Load Limit option
– and finally you could also set “Check each link” option in “General” settings of the plugin to more than it is know; for example if it’s set to 24 hours try setting it to 72 hours or more
Best regards,
Adam
