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

Re: So many ndo2db processes
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

Re: So many ndo2db processes
This is not normal, you have 3 parent processes
Lets stop ndo2db and then run
Lets stop ndo2db and then run
Code: Select all
service ndo2db stop
killall -9 ndo2db
service ndo2db start
Re: So many ndo2db processes
Thanks,
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
