--------------------------------------
Component/s: Core
> flood of "setting live ratio to maximum of 64" from repair
> ----------------------------------------------------------
>
> Key: CASSANDRA-7467
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7467
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Jackson Chung
>
> we are on 2.0.8
> running with repair -pr -local <KS>, all nodes on i2.2x (60G ram);, with
> setting 8G of heap. Using java 8. (key cache size is 1G)
> On occasion, when repair is run, the C* that run the repair, or another node
> in the cluster, or both, run into a bad state with the system.log just
> printing ""setting live ratio to maximum of 64" forever every split seconds.
> It usually happens when repairing one of the larger/wider CF.
> WARN [MemoryMeter:1] 2014-06-28 09:13:24,540 Memtable.java (line 470)
> setting live ratio to maximum of 64.0 instead of Infinity
> INFO [MemoryMeter:1] 2014-06-28 09:13:24,540 Memtable.java (line 481)
> CFS(Keyspace='RIQ', ColumnFamily='MemberTimeline') liveRatio is 64.0
> (just-counted was 64.0). calculation took 0ms for 0 cells
> Table: MemberTimeline
> SSTable count: 13
> Space used (live), bytes: 17644018786
> ...
> Compacted partition minimum bytes: 30
> Compacted partition maximum bytes: 464228842
> Compacted partition mean bytes: 54578
> Just to give an idea of how bad this is, the log file is set to rotate 50
> times with 21M each. In less than 15 minutes, all the logs are filled up with
> just that log. C* is not responding, and can't be killed normally. Only way
> is to kill -9
