> Reporter: zhu
> Priority: Major
>
> run 1.15.2 flink session on k8s，In most cases, there is no problem.
> Sometimes, tasks are initialized continuously, and subsequent tasks are also
> initialized continuously，
> I run batch job with 6 concurrent,jobmanage with 2cpu and 3g Memory
> This problem always occurs, it seems that there is a deadlock during
> initialization, but my job does not have any deadlock issues
