I'm so sorry for the late reply. It seems that the log of indexcoord is not complete, I can't see any index-related logs in indexcoord. Apologize again that I didn't focus on this issue. @JackLCL

[longjiquan]

$ cat indexcoord.log | wc -l
45100
$ cat indexcoord.log | grep "watchMetaLoop" | wc -l
45100

why close this issue, I faced this bug as well. It's not hard to reproduce this issue, just do as your document says https://milvus.io/docs/v2.1.x/example_code.md

Same here, ran into this issue. It seems like sometimes queries hang forever even given some client timeouts. Would be good to understand what's going on and see errors.

this issue was verified fixed on 2.2, please retry on 2.2.2, and if it reproduced to you, feel free to file a new issue with full milvus logs.

I got the same issue with pymilvus 2.3.6. Any suggestion?
