[Xymon] /var/lib/xymon/rrd folders growing larger than anticipated

Morning all,
We are currently running Xymon 4.3.28-1.el7.terabithia (on CentOS 7.x) and
I have been struggling with this since we switched to the RPMs from an
older version of xymon built from source about a year ago. We've gone from
a few GB on the old server to now almost 40GB just for this directory.
I posed the question a little while back to the group and thought I had
found the cause in the rrddefinitions.cfg file under the line:
RRA:HWPREDICT:8064:0.1:0.0035:2016
I tried a few different things but ended up deciding to comment out this
line to see if it would slow the growth, but it does not appear to be
working. Is there any reason these files would be increasing in number or
size? Is there something I can do with rrdtool to clean up data? Is it
normal that an rrd directory for a single host is upwards of 60M on the
newer versions of Xymon?
Here is an example of the files in a folder for a host:

3.5M /var/lib/xymon/rrd/server.example/vmstat.rrd
Do these look like reasonable file sizes/number of files compared to
everyone else? How much space should we reasonably expect to use for this
given we have roughly 1k hosts being monitored (mix of Windows and Linux).
