------------------------------------------
Summary: Ref bug in Scrub
Key: CASSANDRA-13873
URL: https://issues.apache.org/jira/browse/CASSANDRA-13873
Project: Cassandra
Issue Type: Bug
Reporter: T Jake Luciani
I'm hitting a Ref bug when many scrubs run against a node. This doesn't happen
on 3.0.X. I'm not sure if/if not this happens with compactions too but I
suspect it does.
I'm not seeing any Ref leaks or double frees.
To Reproduce:
{quote}
./tools/bin/cassandra-stress write n=10m -rate threads=100
./bin/nodetool scrub
#Ctrl-C
./bin/nodetool scrub
#Ctrl-C
./bin/nodetool scrub
#Ctrl-C
./bin/nodetool scrub

Eventually in the logs you get:
