You could be hitting limits for the number of open files a process is allowed to have, or the limit on the total number of files the system can have open.

Please provide the output from:

Code: Select all

su - nagios -c "ulimit -Sn; ulimit Hn"

Code: Select all

lsof -u nagios | wc -l
and

Code: Select all

sysctl fs.file-nr

I am with @Stuart Watts I believe you could be hitting a open file or open process limit

regards
attached the output of the commands, as I can do to solve it? How much is the limit, I have many services / hosts?

[root@nagiosxi-64 ~]# su - nagios -c "ulimit -Sn; ulimit Hn"
1024
-bash: line 0: ulimit: Hn: invalid number
[root@nagiosxi-64 ~]# lsof -u nagios | wc -l
-bash: lsof: command not found
0
[root@nagiosxi-64 ~]# sysctl fs.file-nr
fs.file-nr = 2368 0 1621016

Looks like you may have increased your open files limit already, what is the output of:

Code: Select all

cat /proc/sys/fs/file-nr
Try running that every 5 minutes 3 times or so and share the output. Thanks!

I also noticed that when I had you tail the nagios log it said it did not exist? Is this true? What is the output of:

Code: Select all

ll /usr/local/nagios/var/
