Subject [jira] [Commented] (CASSANDRA-16106) BufferOverflow exception while writing response to buffer
Date Thu, 12 Nov 2020 18:12:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-16106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17230838#comment-17230838
] 

David Capwell commented on CASSANDRA-16106:
-------------------------------------------

[~yifanc] thoughts?  Looking closer it looks like we try to write more than we allocated,
where as the other one we write less; so possible different issue still?
