把现有的collection全部删除，保证只有一个collection，并且只load一个collection。search还是不返回，请教下我们应该保证空闲内存多少才可以正常search @weiliu1031 ``` 2022-08-03T12:19:21.968498854Z [2022/08/03 12:19:21.968 +00:00] [DEBUG] [streaming.go:163] ["get segmentIDs by vChannel"] [collectionID=435035479762534401] [vChannel=by-dev-rootcoord-dml_131_435035479762534401v1] [partitionID=435035479762534402] [segmentIDs="[]"] 2022-08-03T12:19:21.968537853Z [2022/08/03 12:19:21.968 +00:00] [DEBUG] [query_collection.go:1098] ["streaming search"] [msgID=435035503919391708] [collectionID=435035479762534401] ["searched dmChannel"=by-dev-rootcoord-dml_131_435035479762534401v1] ["searched...

> @PEN170 Could you please refer this [script](https://github.com/milvus-io/milvus/tree/master/deployments/export-log) to export the whole Milvus logs for investigation? 有个很奇怪的现象，刚刚我导出了docker logs，有740M，太大传不上来。就 `docker-compose -f docker-compose.yml down` 后重新启动milvus。刚刚建的9W+条的collection没有删除，重新启动后，还能直接load这个collection。 这时候我去search这个9W+条的collection，可以正常返回结果了

@yanliang567 @weiliu1031 很奇怪的现象，难道是我之前没有释放空间吗，就只做了关闭milvus服务、开启milvus服务的操作，同一个collection search就可以正常返回结果了
