Upload chunks/0/3/3127_0_62876: bad_request: Checksum did not match data received (try 1) [cached_store.go:396]

I'm frequently seeing the following message in juicefs's log:

Upload chunks/0/3/3127_0_62876: bad_request: Checksum did not match data received (try 1) [cached_store.go:396]

Configuration:

• local redis for metadata
• remote backblaze (on a relatively slow connection) as object storage
• rsa client side encryption.
• happens regardless of --writeback being used

What does the message mean exactly? Is it a warning signal for data corruption, or just a cache-miss? Is there anything I can do to further debug/resolve the issue?

This message come from the library talking to B2, I think it means data corruption from network, and the server detect it and JuiceFS will upload that again, so don't worry.
