Subject Explanation for Couchdb crash when using _sum reduce?
Date Tue, 22 Feb 2011 23:35:12 GMT
Any thoughts what is causing this?  Happens when I am pulling up the 
View in Futon. Javascript is nothing complicated:

Map function:
function(doc) {
    var key;
    if (doc.item && doc.timestamp) {
       for (var i in doc.item) {
          key = [doc.item[i]["sku"], doc.timestamp];
          emit(key,Number(doc.item[i]["price"]));
       };
    };
};

Reduce function:
_sum

Only 11 documents. Works with _count. Now it just crashes. Using 0.11.2 
on CentoOS5.
