Hi Expert,

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

when I restart autofs, I got error

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

automount automatically unmounts things that are NOT in use after a time... in your case timeout=300. Looks like something was using /proj and /tool. You can use lsof to find out what process(es) is(are) using those.

With regards to "failed to load map", I'm going to guess that the yp map couldn't be found (?) for auto.tool and auto.proj.

Thanks cjcox
