I have apt-get process running on my server and I cannot kill it.
root 26386 99.7 0.0 25588 2844 ? RN 06:52 956:49 apt-get -qq -y update
kill 26386 first, then tried
kill -9 26386 (as root), nothing happened.
I also killed parent process (PPID is now 1, i think init collected it). The process is still running and the worst thing - it consumes lot of cpu time. The only think I can do with it is lower its priority.
I cannot understand, why kill -9 isn't working. I just thought, it's only signal for kernel to clean the process and the process can't do anything with it. Am I wrong?
I'm using Ubuntu server 12.04 LTS with kernel
3.5.0-34. It's currenty not possible to reboot the whole machine to resolve this problem...
Any ideas how to kill this process? Or is this bug in kernel?
Thanks for any ideas.
