Vladimir Dobos updated CAMEL-16857:
-----------------------------------
Description:
When breakOnfirstError is enabled in camel-kafka, there is visible thread leak
(one hung heartbeat thread per kafka client restart/route retry) in underlying
kafka client, accompanied by small memory leak, for extreme example - see
attached VisualVM screenshots).
Example application used for screenshot can be found in [link
|http://example.com/]] [https://github.com/vdobos-tr/camel-kafka-on-error-leak]
[|http://example.com/]].
We are relatively new to kafka so im unable to determine, if its issue with
underlying kafka client, or problem with the way camel handles reconnect after
error.
