Subject [jira] [Commented] (KAFKA-6689) Kafka not release .deleted file.
Date Wed, 21 Mar 2018 13:56:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6689?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16407938#comment-16407938

huxihx commented on KAFKA-6689:
-------------------------------

[~Ueng] I believe this issue actually results from the same root cause with [KAFKA-4616|https://issues.apache.org/jira/browse/KAFKA-4614],
both of which failed to release the mapped buffers until they were finally garbage collected.
Could you upgrade Kafka to 0.10.2.0 to see if it ever happens?

I can
