Ds 0:08.06 nntpcached: waiting for connections (nntpcached) Any ideas how to kill this? The man page for ps says this for the 'D' state: D Marks a process in disk (or other short term, uninter- ruptible) wait. It's been stuck in this "short term" state for at least 12 hours. kill -HUP, -TERM, -9 etc does not work, presumably because it's uninterruptable. Note that it still accepts inbound connections, presumably a function of the kernel (since it has an open listen socket?) but after connect it's effectively dead. Last time this problem happened I ended up rebooting the machine because everything I tried (including swearing and hitting the keyboard) could NOT remove this task, rendering this reasonably important service unusable, so I'd like to know if there's a better way. :-) If a reboot is the only option, then I sure hope it's not going to keep happening... is there any way I can debug this to work out why it's freezing? Could it be signifying a hardware problem? (Other processes on the machine, including a heavily used Squid with lots of disk access, work fine). The application was compiled about 5 months ago and has only played up like this once before, just over a week ago - before that it was working flawlessly. :-( Thanks...
