The QUERY_FREE_SPACE_LIST is only needed if there is something in the
theme that shows disk usage, so you probably can disable it completely
if you don't care about disk usage being reported in the UI. The only
real caveat is that this is probably functioning as a keep alive so
you may get significant pauses when using the UI after several hours
of inactivity if you disable it fully.

PS This shouldn't be showing up in your logs unless you have debugging
level logging set up & mythtv may run poorly when too much logging is
used.
