[Xymon] Ghost client problems

Hi,
That one i have solved it, but....
Now i have reinstallled the client and i started it using ./runclient.sh --hostname=host start command from xymon user.
On the xymon server web page all the tests(disk,cpu etc) appear in violet colour and i see there the last report i had from when it functioned ok.
On the client i have issued some commands and you have the output here:

[root at otpproxy1 tmp]# ps -ef | grep xymon
xymon     3785     1  0 09:44 ?        00:00:00 ./bin/xymonlaunch --config=./etc/clientlaunch.cfg --log=./logs/clientlaunch.log --pidfile=./logs/clientlaunch.otpproxy1.pid

[root at otpproxy1 tmp]# ps -e | grep xymon
 3785 ?        00:00:00 xymonlaunch
[root at otpproxy1 tmp]# ls -l
total 36
-rw-rw-r-- 1 xymon xymon 32690 Feb 27 13:54 msg.otpproxy1.txt
-rw-rw-r-- 1 xymon xymon   246 Feb 27 13:54 xymon_vmstat.otpproxy1.5867
[root at otpproxy1 tmp]#

As i see there are some files missing from tmp directory. I don't understand why.
Can you please give me a hint?
Regards,
Traian.

A simple ps -ef | grep xymon will show what xymon 
processes are running and which user is running them.
 
Look for 2 instances of 
xymonlaunch.

Hi,
This is my original question.
If i knew the 
        answer i shouldn't ask for help.
I don't know where to check and what 
        to check.
Regards,
Traian.

          Why are the FQDN named files owned by root? this 
          would seem to indicate that root is running commands to output those 
          files? xymon client should be running as the xymon user only. Is 
          something else on your system starting up a second instance of the 
          client?

                Hi,
I have manually compiled it.
I start 
                  it using ./runclient.sh --hostname=otpproxy1 start 
                  command.(otpproxy1 is the client name in hosts.cfg)
Here 
                  you have the commands i gave:

                    How did you install the client, manual compilation or 
                    from one of the RPMs that others have built?

If you 
                    did it manually then in your init script add --hostname=XYZ 
                    as a parameter to runclient.sh (this does appear to map to 
                    the MACHINEDOTS variable inside 
                    runclient.sh).

                          Hi,
I don't find any CLIENTNAME 
                            variable, but i have MACHINEDOTS variable in the 
                            runclient.sh which is said to be "# This systems 
                            hostname".
I changed it to use 'hostanme -s' and 
                            still the same result as in the first message.
I 
                            have these files in tmp folder:

Do you have any explanation why i have all 
                            these files? Shouldn't it be only one named 
                            msg.otpproxy1.txt and not the second named 
                            msg.otpproxy1.temenosgroup.com.txt?

                              To use the shortname just change the

                              with what you have in the main 
                              bb-hosts/hosts.cfg.

If i want to use the short

What config files from

Simple stuff first, do you have 
                                the client listed in ~/server/etc/hosts.cfg 
                                ?

A little clarification: ghost clients 
                                are generally clients that are sending data to 
                                the server, but the server is not configured to 
                                display them.
