Abnormal behaviour of Defuncts
Hi,
I am facing problems with defunct processes. The problem is, the defuncts are being created and getting dissappeared by themselves.
I have a process that calls some scripts through a specified port, when this scripts starts executing, the defuncts also started to appear(lots and lots, will be more than 1000 at times) and are getting dissappeared as soon as the scripts are completing. Those scripts collect system health info executing the commands like prstat, sar, etc..
This is happening only once in a day, at the time of these scripts getting executed.
This server is a part of cluster, hence i had checked the behaviuor in the other server where i couldn't find any problem with the scripts?
Is this some thing related to the performance of server?
It is normal that defuncts will appear when those scripts come into picture but only few(not more than 10).
Can anyone advise?

Hi,
Recently from the vmstat output in the image attached, the first line of the cpu idle column shows a value of 15. Although the subsequent values show higher than 90, is there a reason why the first value is so low?
Is this a problem?
Thanks. (4 Replies)

NAME
cds_intro - Introduction to the CDS commands
DESCRIPTION
The DCE Cell Directory Service provides the following management commands: The cdsbrowser command starts the CDS Browser utility. This
utility is based on the OSF/Motiftm graphical user interface. The Browser can display an overall directory structure as well as show the
contents of directories. The cdscp command starts the CDS control program. Use this command line interface to manage the CDS components
and the contents of your namespace.
The following commands are typically started automatically by scripts that execute as part of normal system start-up procedures. See the
reference pages for these commands before you try to use them. The cdsadv command starts the advertisement and solicitation daemon on the
local system and then starts clerks as needed by applications. Use this command only when troubleshooting because it creates and automati-
cally starts the CDS clerk whenever the host system is rebooted. The cdsd command restarts the CDS server. Use this command only when
troubleshooting because it starts the CDS server process automatically whenever the host system is rebooted. The gdad command starts the
GDA (Global Directory Agent) daemon. The GDA enables intercell communication, serving as a connection to other cells through the global
naming environment. The GDA is typically started automatically by scripts that execute as part of normal system start-up and shutdown pro-
cedures.
