compactor_died while loading data and querying view

6 nodes with approx 90k docs

 While loading docs and querying the view one of the servers goes offline and all subsequent requests to my view is hanging without timing out:

In the diags from 10.1.2.104 I see:
** When Server state == {file,<0.26053.0>,<0.26054.0>,31672309}
** Reason for termination ==
** {compactor_died,
       {{compact_filter_error,{error,badarith},{part_id,dups},{cbitmask,0}},
        [{couch_set_view_compactor,'-compact_group/5-fun-1-',2},
         {couch_btree_copy,fold_copy,3},
         {couch_btree,stream_kv_node2,8},
         {couch_btree,stream_kp_node,7},
         {couch_btree,fold,4},
         {couch_btree_copy,copy,3},
         {couch_set_view_compactor,compact_view,5},
         {lists,mapfoldl,3}]}}


In addition, I failed over 10.1.2.104 because it went down, and when it became reachable, I attempted to rebalance it back but this task is also hanging at about 99%. Fillipe, sorry wasn't able to get debug stats for this run.
