Zhu Zhu commented on FLINK-20220:
---------------------------------
Thanks for sharing the log [~rmetzger]. I checked it and the fatal error cause
is what I guess.
[~trohrmann] yes, we should fix it for both 1.11 and 1.12.0.
I will prepare a fix for it.

> It seems that the purely coordination-related {{updateTaskExecutionState}}
> call doesn't go through because some user data is piggybacking this call.
> I see the following options solving this:
> a) Don't use the coordination RPC system for transferring user payload
> b) use separate RPC calls for transferring user payload
> c) limit the size of accumulators that can be attached to the
> {{TaskExecutionState}}
