There's two problems I'm seeing, one is with map/reduce, the other is that the server will crash under the load the tests put on it (I'll send a separate email with steps to reproduce).

Here's an example of a problem I'm seeing in M/R (from an earlier message):

I'm seeing some weird behavior with map/reduce in 0.13 versus 0.12 and I'm not sure what's going on here. I'm hanging out in the chat room right now trying to find out, but basically, if I run this test case against 0.13 I get a completely different result than what I get in 0.12:

In 0.12, I get [1] in 0.13 I get [2].

The output I'm logging looks like this for 0.12:

11/23/2010 (13:39:47): map={"bucket":"test","key":"test","vclock":"a85hYGBgzGDKBVIsTE+lb2UwJTLmsTLUTEk4xpcFAA==","values":[{"metadata":{"Links":[],"X-Riak-VTag":"5qaBBTXfdEQUyCBTDRRIQ7","content-type":"application/json","X-Riak-Last-Modified":"Tue, 23 Nov 2010 19:39:40 GMT","X-Riak-Meta":[]},"data":"{\"test\":\"value\",\"integer\":12}\n"}]}
11/23/2010 (13:39:47): reduce=[1]

And this in 0.13:

11/23/2010 (13:46:52): map={"bucket":"test","key":"test","vclock":"a85hYGDgzmDKBVIsjDI+7RlMiYx5rAz9ExKO8UGE2ZqTWGZL10AlRCfBJVgYLplNxhQGqmeMbn4EldBEUs/k7LodUxionils9l2oRBGy+cHJ7zGFgeqZk3faQCVOT0aoZzG1PohFmNWr8CxUWGUaijFv+lYiS2QBAA==","values":[{"metadata":{"Links":[],"X-Riak-VTag":"If4qIgutNTerbEmxiKLhR","content-type":"application/json","X-Riak-Last-Modified":"Tue, 23 Nov 2010 19:46:44 GMT","X-Riak-Meta":[]},"data":"{\"test\":\"value\",\"integer\":12}\n"}]}
11/23/2010 (13:46:52): reduce=[]
11/23/2010 (13:46:52): reduce=[1,0]

I tried Homebrew (OS X 10.6) and the OS X download packages of both versions.
