I wonder if inode checks has somehow been disabled. If you go to where 
you compiled Xymon, then in the xymon-4.3.X/lib directory there is a 
"loadhosts" binary. This is a debug module. Could you try running

    cd xymon-4.3.12/lib
    ./loadhosts @ <hostname>
    Pick item: XMH_HOSTNAME
       ... should show the hostname ...
    Pick item: XMH_NOCOLUMNS
       ... should say 'XMH_NOCOLUMNS not found' ...

If it lists "inode" in XMH_NOCOLUMNS, then that is the problem.


If not, then try doing "kill -USR2 <pid of xymond_client>" - this 
toggles the debugging flag in xymond_client. It will start logging  a 
lot of output to clientdata.log - does it show any messages with "Inode 
check" ?

You can turn off the debugging with the same kill-command.
