[CX] Posting multiple requests using curl command to http://localhost:8095/analytics/service hangs

After starting the local cluster on my centos box, I tried issuing curl command:

curl -s --data pretty=true --data format=CLEAN_JSON --data-urlencode statement@file.txt http://localhost:8095/analytics/service

where file.txt contains:

drop dataverse couchbase;

create dataverse couchbase;

use couchbase;

create type `value` as open{};

create type meta as open{

 id:string,

 vbid:int32,

 seq:int64,

 cas:int64,

 expiration:int32,

 flags:int32,

 rev:int64,

 lock:int32

};

create dataset multiple(`value`) with meta(meta) primary key meta().id;

create feed multiple_feed using `com.couchbase.analytics.CouchbaseConnectorFactory`(

 ("bucket"="multiple_table_db_4676_simple_table_1"),

 ("nodes"="127.0.0.1"),

 ("password"="")

 );

connect feed multiple_feed to dataset multiple;

multiple_table_db_4676_simple_table_1 is name of the bucket in cluster.

1. I got this error once:

{

	"requestID": "2700f165-4b65-46ef-9a6b-9a68375cd719",

	"signature": "*",

	"errors": [{ 

	"code": "1",

	"msg": "Failure in feed"

	}],

	"status": "fatal",

	"metrics": {

		"elapsedTime": "536.714096ms",

		"executionTime": "535.300588ms",

		"resultCount": "0",

		"resultSize": "0"

	}

}

2. Second time, it succeeded:

{

	"requestID": "032ec438-b13b-4e07-ae2b-47f66f9dc346",

	"signature": "*",

	"status": "success",

	"metrics": {

		"elapsedTime": "680.375608ms",

		"executionTime": "679.710953ms",

		"resultCount": "0",

		"resultSize": "0"

	}

}

3. Tried issuing same curl command 3 more times, it hangs in 3rd or 4th time. 

Attaching logs.
