Hi,
Are you using 1.4.5? I'm not sure but you may have a log message like this:
"Error occurred trying to query from time 0 to ~p in gc key index. Reason: ~p"
in console.log. If so, it's even failing not only GC but in listing
objects to be collected. Then setting a line
{gc_pagenated_indexes, true},
into riak_cs section of your app.config . This is implicit option and
its default is false.
