The process_results function in riak_pipe_qcover_fsm incorrectly returns {{error, Reason}, State} when it should return {error, Reason}. The qcover module implements a coverage FSM that is driven by riak_core_coverage_fsm, which passes the error from process_results to the finish function, which expects {error, Reason}. This problem manifests itself with the following match failure:
[error] <0.28297.0> CRASH REPORT Process <0.28297.0> with 2 neighbours crashed with reason: no function clause matching
riak_pipe_qcover_fsm:finish({{error,worker_limit_reached},
{state,{raw,408228,<0.28284.0>}}},
{state,{raw,408228,<0.28284.0>}})
