Why are they? You've got some workload that is mixing direct IO writes with some form of buffered or mmap IO on the same file and they are racing. Mixing different types of IO on the one inode is also known as A Really Bad Idea because there is no guarantee of coherency between them.... Can you find out what the application is triggering this?
