Hi, I've got the same problem
Upgraded from 2.2.11 to 3.11.3 and since then the DEBUG logs shows this
messages.
Seems to me that after the repair the messages were reduced a little, but
it's still happening.
In my case is a 3-node cluster, RF3, reads and writes with LOCAL_QUORUM

I upgraded from 2.1 to 3.11 and started to get huge number of Digest
mismatch errors in the DEBUG log. I ran a full repair in the cluster but
it did not seem to cut back on these.
My consistency is QUORUM so my guess is this error is on reads but would
this also affect my writes to all replicas
