Did you rtfm ipcs? And presumably the grep is yours rather than copied blindly from something you googled? (you never know on this list, you get the occasional poster who will cut&paste something like that without understanding why their box is different). > "apachectl graceful" If ipcs finds anything, you might want to check if it coincides with the cron. That would happen if it isn't exiting cleanly and might be fixed by an upgrade of your server, or something running under it. -- Nick Kew --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
