Subject Re: Huge number of Mismatchs in the logs
Date Wed, 30 Jan 2019 18:18:37 GMT
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
