Environment Setup

• Server: parse-server version: 2.2.10, operating system: ubuntu 14.04, local
• Database: MongoDb 3.0.12

Steps to reproduce

1. define Cloud function
   Parse.Cloud.define('test', function(request, response) { (new Parse.Query('_User')).select('username').limit(2).find().then( function(r) { return (new Parse.Query('_User')).select('username').skip(2).limit(2).find(); } ).then( function(r) { response.success(r); }, function(error) { response.error(error); } ); });
2. run it
3. wait 120 seconds (it's default value for "server.socketOptions.connectTimeoutMS" and "server.socketOptions.socketTimeoutMS" of "databaseOptions" value of ParseServer config.
4. run function again. result is:
   curl: (52) Empty reply from server

I found that if the second query's limit is more than 1 in "test" cloud function, then auto-reconnection of database fails.

Here's log of mongod.log:

and it's not starting again :(

I have same issue too, parse server stop return data from mongodb after some minutes.

Possibly related to this? #1854

[chris3000]

I'm having a similar issue, when testing the server under load. After the load test completes, the connection between Mongo and Parse will disconnect after a couple of minutes.

I think this is a duplicate of #1854 and #1855. Pin your mongodb version to 2.1.18 and your problem should be fixed.
