[KevinDW-Fluxys]

Describe the bug We are getting regular warnings 2023-08-17T06:03:53.419113901Z stderr F ts=2023-08-17T06:03:53.341803178Z caller=spanlogger.go:85 user=logs-infra-man-dev method=ChunkStore.FetchChunks level=warn msg="could not store chunks in chunk cache" err="the async buffer is full"

However we are not using caching (see config below)

To Reproduce Steps to reproduce the behavior:

1. Started Loki (2.8.4)
2. Query Logs: {namespace_name="loki"} | logfmt | level != "info" | level != "debug"

Expected behavior No warnings regarding to caching when not using caching.
