bartvandermark on "[Plugin: WP Super Cache] Cache preload starts too often (20 times per day)"

WP supercache works, but I have the following problem: I have set the option 'Refresh preloaded cache files every' to 720 minutes (12 hours). My blog is pretty static, I make new blogposts every 2 weeks on average.

But WP super cache starts preload about 20 times per day (!). Something causes wp supercache to start the preload way too often and I can't figure out what causes this.

I suspect the 'addlink2facebook' plugin might cause this? It checks for FB comments on my FB businespage and it imports the FB comments as WP comments on the blogposts. But I have set the setting to check every 2 hours and 99% of the time it won't find new FB comments to import.
