Status.log file disappears?

[Thomas Quinlan]

Hi,

Your information got me thinking... I didn't know
exactly when the file was being "erased".  It turns
out that it goes away when Nagios is *stopped*.  If I
stop Nagios, create the file, and then start Nagios,
the file is there.  (It never goes above 0 bytes
though.)  If I stop Nagios, the file disappears.

Here is how I create file:

cd /var/nagios
touch status.log
chown nagios.nagios status.log
chmod 0777 status.log

ls -al shows:

drwxrwxr-x    4 nagios   nagios        248 Apr  6
13:29 .
drwxr-xr-x   15 root     root          384 Mar 17
02:29 ..
-rw-r--r--    1 nagios   nagios          0 Dec  3
23:41 .keep
drwxrwxr-x    2 nagios   nagios        392 Apr  6
00:00 archives
-rw-r--r--    1 root     root            6 Apr  6
13:27 nagios.lock
-rw-r--r--    1 nagios   nagios    3779904 Apr  6
13:29 nagios.log
drwxrwsr-x    2 nagios   apache         72 Dec  3
23:41 rw
-rwxrwxrwx    1 nagios   nagios          0 Apr  6
13:29 status.log
-rw-r--r--    1 nagios   nagios          0 Apr  6
13:27 status.sav

So I can see the file is there, and that the
permission s I gave it are correct... and I can start
Nagios and it will stay there.

Then I do /etc/init.d/nagios stop, and ls -al shows:

drwxrwxr-x    4 nagios   nagios        248 Apr  6
13:29 .
drwxr-xr-x   15 root     root          384 Mar 17
02:29 ..
-rw-r--r--    1 nagios   nagios          0 Dec  3
23:41 .keep
drwxrwxr-x    2 nagios   nagios        392 Apr  6
00:00 archives
-rw-r--r--    1 root     root            6 Apr  6
13:27 nagios.lock
-rw-r--r--    1 nagios   nagios    3779904 Apr  6
13:29 nagios.log
drwxrwsr-x    2 nagios   apache         72 Dec  3
23:41 rw
-rw-r--r--    1 nagios   nagios          0 Apr  6
13:27 status.sav

And the file is gone.

If I leave the ownership as root.root, the file still
disappears.  If I change the permissions to anything
else, as either owner, the file disappears when Nagios
is stopped.

I tried entering some text into the file, thinking
that Nagios might not like a 0 byte file, but that
didn't make a difference either.
