[resolved] too many tags causes wp-admin issues (4 posts)

    having trouble with the super cache garbage collection routines. wp-content/cache/supercache/{site}/tag has too many files in it, so the gc routine times out or crashes, causing wp-admin/post-new.php to return a white screen. in this case, the tag dir had ~33k files, and the ls -ld of the tag dir showed the dirent to be ~7M in size. it should also be mentioned that the site that uncovered the issue uses an automatic tagging plugin, so it has a rather large number of tags (almost 1 million), but i suspect this problem would likely affect sites with large numbers of posts (or other content) as well.

    Are the cached tags generated by the preload?

    If you have preload mode on then turn it off and schedule the garbage collection a lot more often so the number of files don't build up so high.

    I think that I may have a similar issue where wp-admin/post-new.php times out when there are a lot of cached files, and things work fine again when I clear the cache. Note that it doesn't always time out, but it tends to time our more often and longer when the cache is busy. In my case we never had issues with WP SuperCache 0.999.
