Hi Robert,
do you have some additional info? For example the last log message of
the unreachable TaskManagers. Is the Job running in kubernetes? What
backend are you using?
From the first looks of it, I have seen this behaviour mostly in cases
where one or more taskmanagers shut down due to GarbageCollection issues
or OutOfMemory-Errors.
Best regards
Jan

I have a job that fails after @1 hour due to a TaskManager Timeout.
How can I prevent this from happening?
