Hi,

We are seeing some AntiEntropy error in our production servers, since =
it's hard to repro in other env, pasting the stack track here for some =
clue.=20

We're using a cluster of 2 data centers, 9 nodes, 6 for online traffic, =
3 for Brisk BI. Our RF is Cassandra:5, Brisk:1.

The exception stack is appended in the end.

Any help is appreciated.

Thanks,
Hefeng
