spamdyke does not "read from itself" while running. Most operating systems lock executables while they are in use; this has been a standard practice for the last several decades. The same is true of libraries that are in use by running processes. You can't overwrite the qmail executable while it runs either, the difference is that qmail-smtpd probably isn't running nearly as much as spamdyke is.
What version of spamdyke are you using? Version 3.1.4 fixed a bug that would cause 100% CPU usage in certain situations. -- Sam Clippinger N.Novozhilov wrote: > Question is in subject. > > Results: > 1.
