Current Behavior

I can create a collection about 3M vectors of dim 512, IVF_FLAT index and do search well on the collection. However, after releasing the collection, it seems hard to load the collection again to query nodes. The query nodes might be stuck at loading segments. Below is log i get from query coord and query nodes at loading time.
