It's funny - I was just bit today by this problem :( Today, my work machine stopped sending out emails. After some frustration, I was able to find the cause of this problem - sendmail refused to process its queue because the load level was too high. 54, actually... Needless to say, nothing was actually running and spending CPU. Apparently some NFS connection of mine got stuck, and various cron jobs that did things like "updatedb" and "df" got indefinitely stuck in the D state. So I had to reboot my (330 day uptime...) machine. I couldn't even cleanly shut it down, because the NFS unmount never finished. This is definitely a Linux bug. Maybe it was fixed in 2.6 (as you can guess from my uptime, I'm running an old system here). -- Nadav Har'El | Tuesday, Apr 5 2005, 25 Adar II 5765 [EMAIL PROTECTED] |----------------------------------------- Phone +972-523-790466, ICQ 13349191 |If glory comes after death, I'm not in a http://nadav.harel.org.il |hurry.
