Describe the bug

When I try to create two connections to separate instances of milvus, in the same execution, I get errors.

Expected Behavior

I expect to be able to make both connections successfully.

Steps/Code To Reproduce behavior

When I execute the following code:

import uuid
from pymilvus import (
    MilvusClient,
    connections
)

a_name = str(uuid.uuid4())[:8]
collection_name = "test_collection"
milvus_uri = "http://milvus:19530"
connections.connect(alias=a_name, uri=milvus_uri)
client_1 = MilvusClient(milvus_uri, alias=a_name)

a_name = str(uuid.uuid4())[:8]
collection_name = "test_collection"
milvus_uri = "http://10.57.202.36:19530"
connections.connect(alias=a_name, uri=milvus_uri)
client_2 = MilvusClient(milvus_uri, alias=a_name)

I get this error:

Environment details

- Hardware/Softward conditions (OS, CPU, GPU, Memory):
- Method of installation (Docker, or from source):
- Milvus version (v0.3.1, or v0.4.0):
- Milvus configuration (Settings you made in `server_config.yaml`):

Anything else?

No response

It's not recommanded to use connections together with MilvusClient. c = MilvusClient(uti="http:/localhost:19530") will connect with the server too.
