-----------------------------------------

             Summary: Memory Leak in HTTPMetricHandler when reporting fails
                 Key: FLINK-31372
                 URL: https://issues.apache.org/jira/browse/FLINK-31372
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Kafka, kafka
    Affects Versions: 1.15.0, 1.15.1
            Reporter: Krzysztof Dziolak


Basically I'm running flink at the 1.15.1 version with docker  and often the application start to slow down because of OOM errors. 
It was observed that the memory continued to increase, and the number of threads continued to increase through the mertics data collected by Prometheus。
I tried to remove the sink kafka code and it looks normal,so I change the flink to 1.14.5 and it works fine.
Is this a bug?
