I am trying to restart automount as it's consume much CPU. Tasks: 2392 total, 7 running, 2352 sleeping, 25 stopped, 8 zombie Cpu(s): 9.3% us, 28.5% sy, 0.0% ni, 61.5% id, 0.2% wa, 0.2% hi, 0.2% si Mem: 15799928k total, 11029764k used, 4770164k free, 162424k buffers Swap: 22773752k total, 7303680k used, 15470072k free, 2628508k cached

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5939 root 25 0 27112 1556 952 S 97.2 0.0 3155:01 automount

when I restart autofs, I got error

Your assistance in this matter is very much appreciated. Thx.

  • If reboot an option, I will go for that. Anyway, what OS is this? – Muhammad Oct 1 '10 at 7:15

And try to kill automount first before restarting autofs.

If you can't kill it, then a reboot is a must. Try to "kill -15 5885" and not "-9", where 5885 is the autmount pid as per above.


I wouldn't kill it i were you :> Propably an application is using /proj (in terms of open files), and if you umount it you may have a really bad experience.

Try to find which application this is (using lsof) , kill the application and try to umount the directory afterwards.

  • +1 for lsof... a good app – Muhammad Oct 6 '10 at 12:00
