Does it not work on the queue > until all items are loaded? Cache _loader_ never deletes anything. It loads information about the cache from disk. If it's running, it means that information about the cache wasn't yet loaded and nginx can't maintain configured max_size as it don't know current cache size (yet). In contrast, cache _manager_ maintains max_size and deletes inactive cache items. It will not be able to maintain max_size till the cache is loaded, see above. > Is there anything I can do to try to alleviate this problem? If you have problems with IO, most trivial solution to try is to reduce IO with proxy_cache_min_uses, see http://nginx.org/r/proxy_cache_min_uses. -- Maxim Dounin http://nginx.org/en/donation.html _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
