Hello All,

I'm getting the below error in my queries. I'm using riak 1.1.1

Riak Version:
============
$rpm -qa | grep riak
riak-1.1.1-1.el6.x86_64

Riak Error:
========
HTTP/1.1 100 Continue
HTTP/1.1 500 Internal Server Error
Server: MochiWeb/1.1 WebMachine/1.9.0 (someone had painted it blue)
Date: Tue, 24 Apr 2012 16:58:53 GMT
Content-Type: application/json
Content-Length: 625
{"phase":0,"error":"[preflist_exhausted]"

Query:
==========
My query is doing a range scan. I can only get data for 1 day. For 2 or more days it is throwing the error posted above.

{"inputs":{ "bucket":"tagg_dsquery",
            "key_filters":[["and",
                  [["starts_with", "dsquery-us_prm"]],
                  [["and",
                    [["tokenize", "-", 5], ["greater_than_eq", "20120312"]],
                    [["tokenize", "-", 5], ["less_than_eq", "20120314"]]
                  ]]
                ]]},
...
...


app.config changes:
=============
map_js_vm_count - increased to 32,64,128 and 256 but not helping
js_max_vm_mem - increased to 32,64,128,256,512 and 1024.
js_thread_stack - increased to 64,128,256,512,1024 and 2048 (cannot go beyond) - riak would not start

Can anyone help me to debug this issue. My queries cannot go beyond 1 day

Thanks
Mohit
