What should I check, my configuration parameter are as below, A) is the -m ip_address:6123 right option or 8081 should be the port... config..
# Note this accounts for all memory usage within the TaskManager process, including JVM metaspace and other overhead.
taskmanager.memory.process.size: 1568m
# To exclude JVM metaspace and overhead, please, use total Flink memory size instead of 'taskmanager.memory.process.size'.
# It is not recommended to set both 'taskmanager.memory.process.size' and Flink memory.

Is this a right state?
I have faced the same problem in Flink-1.10.0. So please make sure you have enough memory according to the data load.
Error which i was getting:
java.lang.OutOfMemoryError: Metaspace
So I have increased taskmanager.memory.jvm-metaspace.size according to data load and it solved my issue.
