Looks like the filenames are generated from information sent by the 
xymon client running on the host.  I see files with interface names on 
my Xymon server. These are from a client running on a SPARC Solaris system:

rrd/sahara/ifstat.bge1.rrd
rrd/sahara/ifstat.bge3.rrd
rrd/sahara/ifstat.bge2.rrd
rrd/sahara/ifstat.bge0.rrd

I'm running 4.3.23, RPM package built from source.  These ifstat files 
are 38K in size.

I would have guessed that the numbers were IP addresses, but you've got 
two of them in that list starting with zero, and one ending with zero, 
so if those are IP addresses, there may be an invalid address configured 
somewhere.  And if they're not IP addresses, then I have no idea what 
they are, and you may need to look into the client running on the host.

Thanks,
