Hi all,
2187 ?? 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...
Cheers.
