      Description

      Waiting time for write concern increase as time goes by usually within 24-36 hours after restart. The issue disappears when the secondary instances are restarted.

      db.currentOp().inprog.filter(function(op){return op.msg === "waiting for write concern"}).map(function(op){op.ms = op.microsecs_running ? op.microsecs_running/1000 : 0; return op;}).filter(function(op){ return op.ms > 50}).map(function(op){return {ms : op.ms, col : op.ns}}).reduce(function(e, c){if(e[c.col]){e[c.col].push(c.ms)}else{e[c.col]=[c.ms]} return e}, {})
