Connection unexpectedly closed by remote task manager

ApoorvK
I have a flink job running on version 1.8.2 with parallelism of 12, I took
the savepoint of the application on disk and it is of approx 70GB, now when
I running the application from this particular savepoint checkpoint keeps
getting failed and app could not restart. I am getting following error :
Kindly let me know what can I do to get this fix

org.apache.flink.runtime.io.network.netty.exception.RemoteTransportException:
Connection unexpectedly closed by remote task manager
'ip-10-210-5-104.ap-south-1.compute.internal/10.210.5.104:42317'. This might
indicate that the remote task manager was lost.

Re: Connection unexpectedly closed by remote task manager

r_khachatryan
Hi,

Can you check if there are any failures on task manager mention in error message (ip-10-210-5-104.ap-south-1.compute.internal/10.210.5.104:42317)?

Regards,
Roman
