Subject [jira] [Commented] (CASSANDRA-13752) Corrupted SSTables created in 3.11
Date Thu, 10 Aug 2017 18:16:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16122020#comment-16122020
] 

Jeff Jirsa commented on CASSANDRA-13752:
----------------------------------------

Any additional context you can provide - how old is the cluster? Have you changed anything
recently? When did you upgrade to 3.11.0? How long before you saw those errors? Do you run
repairs? Incremental repairs or full? Anything else in the logs that looks atypical?
