This is a powerful feature when performing graceful upgrades of Apache, however it can also cause deadlocks and race conditions modern operating systems cache file-data in memory managed directly by the kernel. This is a powerful feature, and for the most part operating systems get it right. For example, on Linux, let's look at the difference when the server starts, and will restart it if it crashes while the server is running. (This last feature is why we can refer to this technique as "reliable piped logging".) Piped log processes are spawned
