Current Behavior

Streaming service is not stable and crash during nightly tests. link: https://jenkins.milvus.io:18080/blue/organizations/jenkins/Milvus%20Nightly%20CI(new)/detail/master/122/pipeline/139/

The test ended with failure:

[pytest : test] [gw2] [ 23%] FAILED testcases/test_index.py::TestBitmapIndex::test_bitmap_primary_field_data_repeated[2-3791-varchar_pk] 
[pytest : test] [gw3] [ 23%] FAILED testcases/test_index.py::TestBitmapIndex::test_bitmap_primary_field_data_repeated[16-1600-varchar_pk]

[pytest : test] [gw0] [ 23%] FAILED testcases/test_index.py::TestBitmapIndex::test_bitmap_insert_before_loading[varchar_pk-True] 

Maybe the crash has something wrong with bitmap.

Expected Behavior
