I think this may be the problem. I discovered this morning my personal mail server was no longer sending administrative messages. I went to investigate and found the same thing happening there. I have a hard time believing that the same hardware failure could be happening on three completely different (I mean /completely/) machines at pretty much the same time. (I'm surprised the fourth one isn't doing it.) So, I went with the assumption that the kernel was the problem. I changed the default kernel in the GRUB menu file to the previous version listed (from 2.6.22-15-server to 2.6.22-14-server) and restarted the computer. So far it seems to be working fine. There was a glut of e-mails that were being held up that have now been delivered, and the software is not in the weird state it was in before. I'm going to assume for now that the problem has been discovered, and I now have a fix for it. Later today I'll reboot the other three servers (I've already changed the menu.lst file). If it still isn't fixed, I'll start troubleshooting the hardware and report back at that time. Thanks so much for helping me find and solve this problem. -- Jason Flatt Father of Six: http://www.flattfamily.com/ (Joseph, 15; Cramer, 13; Travis, 11; Angela; Harry, 8; and William, 2) Linux User: http://www.kubuntu.org/ Drupal Fanatic: http://drupal.org/ ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
