krsd process taking high CPU usage

Hi All,

 

I am having a HPUX 11iV2 OS. Lately i have noticed that there is a process named "krsd" which takes up very high amount of CPU resource. The time when it is using top resource of CPU, the idle CPU is 0% at that time and it runs for a long time. Does anyone has come across such situation? can i kill the krsd process at the time when it runs with high CPU usage? Anyone has got any solution?

 

Please help......

Re: krsd process taking high CPU usage

Start by reading the man pages for krsd(1m).  Killing it is simply going to cause it to be respawned by init and potentially cause some persistent data not to get written to disk.  I would advise caution.

Thanks Pete for the reply!!

 

i did see the man page, but it does not mentioned any effect of killing the process. i suspect a performance patch should cure the issue. Lets see if it is a known issue faced by some one in the forum........

The latest krsd patch is PHCO_40340, release in 2009.

Re: krsd process taking high CPU usage

The patch doesn't seem to address CPU usage (but you never know):

 

Symptoms: 
	PHCO_40340:
	( QX:QXCR1000951742 )
	krsd(1M) can sometimes log incorrect messages to syslog.

Defect Description: 
	PHCO_40340:
	( QX:QXCR1000951742 )
	The kernel registry services daemon, is asked to save
	data, flagged as persistent in the core kernel KRS tree,
	to files on disk. In a particular scenario, krsd(1M) is
	asked to unconditionally save files on to the disk even
	if no persistent data has changed since the last save.
	This causes error messages to be logged to syslog.

Re: krsd process taking high CPU usage

Shalom,

 

Generally, keeping current on bi-annual patches, known as QPK does help you avoid these types of issues. Having a policy of patching systems twice a wear with QPK is a good policy.

 

I would search the Patch database for this symptom and make sure any solution you attempt is complete.
