So many ndo2db processes

[Nabi]

Hello,

Can anyone please advise why on NAGIOS server we see from time to time so many "ndo2db processes" running, like 12 processes.
NAGIOS looks fine and CPU as well.

Thanks,

Nabi

On a system with a lot of hosts/services this could be expected, as long as they all stem from the same parent process it would not be an issue.

Thanks,
Then i expect in the example below there is an issue:


cec:/home/nh# service ndo2db status
ndo2db (pid 27703) is running...


cec:/home/nh# ps -ef | grep -i ndo2db | grep -iv grep
nagios 10386 1 0 May17 ? 00:00:34 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
nagios 24718 27703 0 May17 ? 00:28:09 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
nagios 24721 24718 4 May17 ? 02:33:27 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
nagios 26274 1 0 May17 ? 00:15:31 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
nagios 27703 1 0 May17 ? 00:00:00 /usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg

This is not normal, you have 3 parent processes

Lets stop ndo2db and then run

Code: Select all

service ndo2db stop
killall -9 ndo2db
service ndo2db start

I figured out that the issue seems to be caused by high load on the server, so it seems when it has high load then more parent processes of ndo2db are running. So i need to fix the load issue first .

Thanks again

Sounds like a good plan
