Too many tasks/process?

Post by wonrhee » 2010/01/12 18:54:15

Hello All,

I could not find an answer to following.

I just did a fresh Centos 5.3 x86_64 bit (server only, no gui) installation on Dell R710 2 x Xeon 5500 (16 cores total)

"top -M" shows below :

Tasks: [b]238 total[/b], 1 running, 237 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 23.532G total, 1958.570M used, 21.620G free, 259.492M buffers
Swap: 25.500G total, 0.000k used, 25.500G free, 1394.113M cached

My question is [b]238 total[/b] . Is this ok?

I did review all the processes and disabled things I didnt needed such as cups, hidd, etc.

For your info, 8 core server runs 115 tasks, 2 core runs 88 total, and 1 core runs 64 total.

I believe it is normal, but just want to make sure.

Thanks in advance.

Welcome to the CentOS fora.

Doesn't look abnormal, although somewhat higher than my lightly loaded severs in a research environment. The number of processes will depend on what the system is doing.

You should not be doing fresh installs of 5.3 - the current release is 5.4. There have been a [b]lot[/b] of security and bug-fix updates since 5.3 so an immediate update is highly recommended. Since kernel and glibc are to be updated, it is recommend to follow the procedure in section 4 of the [url=http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.4]CentOS 5.4 Release Notes[/url] to minimize potential problems with the update.
