Description

we havae a flink job , jst one taskmanger;

when use high presure as soure data,it will be stuck. sometimes it will be run 1d ,somtimes it will be run 30min.

like this: (13:30 the taskmanager reboot,then run 30min, result is stuck )

test 3 cases:

1: low presure (1200eps ),  it will run 30 min or 1d 。

2: close checkpoint , it will run 3d , high presure (1800eps) ，did not run stuck。

3：double the orignal  managermemory, it still stuck, jst The appearance time has been changed to 3 days from 30mins.

 

the threads dump info ,when high presure , cpu 90%~100%:
