[Bug]: After building the search library, when searching, after searching two or three pieces of data each time, the standalone program exits without any error. There is still some memory left, and mmap is enabled.

[DeerEyre]

Is there an existing issue for this?

• I have searched the existing issues

Environment

- Milvus version:
- Deployment mode(standalone or cluster):
- MQ type(rocksmq, pulsar or kafka):    
- SDK version(e.g. pymilvus v2.0.0rc2):
- OS(Ubuntu or CentOS): 
- CPU/Memory: 
- GPU: 
- Others:

Current Behavior

docker-compose milvus2.6.0版本，导入了1500W数据，占用了0.14TB的内存，docker-compose里限制使用了300G内存。使用的是BM25+IVF-RabitSQ的索引
检索库从启动到加载一切正常，每次调用检索超过两三条就会突然崩溃，milvus-standalone就会突然消失。
