Matthias Pohl commented on FLINK-34200:
---------------------------------------
btw. I was able to reproduce the test instability locally after the third run
(keep in mind that it appears to only fail for backend=rocksdb,
buffersPerChannel=2):
{code}
java.lang.AssertionError:
Expected :[(0,8000), (0,32000), (0,48000), (0,72000), (1,78000), (1,30000),

Actual :[(0,8000), (0,32000), (0,48000), (0,72000), (1,78000), (1,30000),

{code}
The actual diff is again 4 events more than expected: {{(0,1000), (0,25000),
(0,33000), (0,41000),}}
