flink-on-yarn Out Of Memory exception

hello,
My task has an "Out Of Memory" exception error after running for 3 hours. The version of my cluster is 1.14.2, the memory allocation of TaskManager is 2g, and the attachment is the log file of jvm's heap memory analysis, which involves the flink framework. So asking for help, thanks!
