milvus: [Bug]: Addition of data hangs after 16 vectors have been inserted

Is there an existing issue for this?

Environment

- Milvus version:v2.0.0-pre-ga
- Deployment mode(standalone):
- SDK version(pymilvus v2.0.0rc2):
- OS(Ubuntu): 
- CPU/Memory: 128G, 32G
- GPU:

Current Behavior

After upgrade to 2.0.0-pre-ga, I need to add data. The addition of data hangs when the 16th vector has been added. The dimension of vector is 128. This issue happened on two servers. Besides ""error=“err: number of RootCoord is incorrec” in the log, there is no other error. However, this error seems a known issue, https://github.com/milvus-io/milvus/issues/14873, and doesn’t seem to be related.

Expected Behavior

Should not hang.

Steps To Reproduce

Add vectors

Anything else?
