Hi Team. I would like to ask some question regarding this error i found on taskmanager log

WARN  org.apache.flink.hive.shaded.parquet.hadoop.MemoryManager - Total allocation exceeds 50.00% (2,130,706,432 bytes) of heap memory

What is the meaning of this error? Does it means that the resource used to write parquet exceeds 50% of HEAP? If yes, what are some root causes that it suddenly occurs after I have ran the job for months. I tried to restart all taskmanagers and everything seems to work fine
