Can anyone download that attachment? JIRA is being weird about it.

>          Components: Database Core
>    Affects Versions: 0.10

> This view used to work on 0.9.1, I've installed 0.10.0 and migrated some data.
> When running the view I get the following error:
>     (env2.5)[11:47] admin $curl 'localhost:5985/stats/_design/stats/_view/active'
>     {"error":"reduce_overflow_error","reason":"Reduce output must shrink more rapidly:
Current output: '[[25,17,117,25,93,17,13,13,12,24,14,13,10,15,20,12,14,14,17,36,38,83,18,11,1058,12,10,29,13,12,10,14'...
(first 100 of 1395 bytes)"}
> What's interesting is that this view does not have a reduce function. The map function
is:
>     function (doc) {
>         if (doc.Type == 'max active') {
>             emit(doc.Time, doc.Count);
>         }
>     }
> A typical document looks like:
>     {"_id":"02c94bea2900686a01ebbf8829aabfa2","_rev":"1-cccb3b5eb382bf609bd41feb85af063b","Count":2,"Type":"max
active","Time":1254362400.0}
