Processes in DNS server

Christian Aguilar Varga — Thu, 26 Jan 2006 19:09:44 GMT

Hello:
We have one DNS server, that is a HP RP2430 platform with SW HP-UX 11.11 (64 bit) and also is running the application DNS Bind 9.2.0 in order to act as a DNS server.
The strange issue is that the % of process CPU is very high and is just because of the process "dmisp". This high percentage has same status even if we restart the DNS (but we haven´t done it lately).
I´m sending the output of the top command.
What is this process for? and why it has so much load consumption? is this a normal behavior?
Thanks in advance,

DNS01

That process is part of Desktop Management Interface (DMI) Service Provider. It's also used by SIM.

Maybe you should upgrate DMI or SIM.

dmisp is part of the Service Control Manager as well as Systems Insight Manager. Since both of these products require a fair amount of configuration and regular monitoring, you would know if you're using either of these two products from HP. You can stop dmisp with the start/stop script:

/sbin/init.d/Dmisp stop

Then edit the file: /etc/rc.config.d/Dmiconfig to set the start variable START_DMI=0. That will eliminate the problem.

I see acouple of other unnecessary processes: scrdaemon and pwgrd. scrdaemon is System Configuration Repository and you would know if you're using it (lots of configs and maintenance). And pwgrd is a passwd file helper. It is only useful if you have hundreds of users in the passwd file. Turn off scrdaemon and pwgrd with:

/sbin/init.d/scrdaemon stop
/sbin/init.d/pwgr stop

and permanently disable them from running on rebootby editing their config files in /etc/rc.config.d: scrdaemon and pwgr

SCR_DAEMON=0
PWGR=0

You can always turn on these features in the future but I prefer to disable products that are not being used.
