This one puzzles me a bit. Supposedly it comes from xymond while 
starting up, but xymond should not have problems loading hosts.cfg.

This is not unusual when Xymon starts. It happens because xymongen (the 
tool that generates the static overview webpages) tries to fetch the 
current status from xymond before it is ready (e.g. because it is 
loading the saved state).

It will run again one minute later and work normally.

These are normal. xymond_channel doesn't start the various worker 
modules (xymond_rrd, xymond_history etc.) until the first message 
arrives, and when that happens it will log this message.

This could be the same core problem as the first log message you've shown.

Are you by any chance running xymond with the "--no-download" option? Or 
do you have a "--admin-senders" option enabled for xymond ?

They shouldn't be, but right now I cannot determine if this is a result 
of the problems with loading the hosts.cfg file.

Could you try changing lib/loadhosts_file.c: Lines 140-144 look like this:

    prepresult = prepare_fromnet();
    if (prepresult == -1) {
      errprintf("Failed to load from xymond, reverting to file-load\n");
      prepresult = prepare_fromfile(xgetenv("HOSTSCFG"), extrainclude);
    }

Change them to just

    prepresult = prepare_fromfile(xgetenv("HOSTSCFG"), extrainclude);

Then do a "make clean; make; make install".
