    I’m getting repeated symlink, race condition errors in my control panel from Comet Cache and wondered if I can resolve them (I’ve removed a portion of the URL for posting):

  • @bigbluesquid The only thing that Comet Cache uses symlinks for is the 404 Error Page caching (Comet Cache → Plugin Options → 404 Requests). Since the 404 Error Page is the same regardless of where it’s loaded from, Comet Cache creates a single 404 Error Page cache file and then symlinks other 404 cache file paths to that original 404 Error Page cache file. This improves performance and saves disk space.

    If your hosting service disables the PHP symlink() function, you can simply disable the 404 Error Caching feature in Comet Cache (see Comet Cache → Plugin Options → 404 Requests) and that should resolve the issue for you.
