[jira] [Commented] (KAFKA-14168) Constant memory usage increase
[ https://issues.apache.org/jira/browse/KAFKA-14168?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17580371#comment-17580371 ]
Greg Harris commented on KAFKA-14168:
-------------------------------------
There are some existing Connect bugs which may leak producers/producer-network-threads:
* https://issues.apache.org/jira/browse/KAFKA-9830
* https://issues.apache.org/jira/browse/KAFKA-13533
Either this is a regression of 9830, a duplicate of 13533, or a novel producer leak. Are you seeing any exceptions in your logs to correlate to the leaked threads?
Can you clarify what this com.dong.task.tt.TaskMainEXactlyOnceKafka3 class is doing? Is this a vanilla Apache Kafka Connect runtime or are you running a custom runtime/fork of Connect? Perhaps this fork doesn't have the KAFKA-9830 patch applied.
