I just upgraded to Mongo 2.6.0 and suddenly started getting intermittent crashes during geo searches. This does not happen all the time, but does happen quite consistently - just a matter of time when under moderate load.

This never happened on the 2.4.x branch, and I'm just wondering if anyone else has run into this problem or it's a known issue that will be fixed in the next patch release?

Here's an example of a search then crash (Mongoose debugging on):

    Mongoose: records.find({ 'locations.geo': { '$nearSphere': [ 82.2, 122.21 ], '$maxDistance': 0.02 } }) { fields: undefined }  
    connection error: [Error: failed to connect to [localhost:27017]]
    #

Let me know if I can provide any more details and how to do so. This is happening both on my Linux dev machine (Arch x86_64) and a colleagues Macbook Pro.
