Christoph Schnepf created CASSANDRA-20664:
---------------------------------------------
Summary: Endless loop on reading commitlogs when it should ignore
replay errors
Key: CASSANDRA-20664
URL: https://issues.apache.org/jira/browse/CASSANDRA-20664
Project: Apache Cassandra
Issue Type: Bug
Components: Local/Commit Log
Reporter: Christoph Schnepf
We specify the option `-Dcassandra.commitlog.ignorereplayerrors=true`, however
we see an endless loop on starting Cassandra when there are corrupt commit log
files found.
The stacktrace which is printed over and over again is:

This prevents the Cassandra startup on this node and it writes 50 MB to the
system.log in about 2 seconds.
