We recently faced high memory utilization on primary RE of Juniper MX. I have attached graph of Memory Utilization . It was as a result for copying some files from Backup RE to Primary RE (This is which I am just guessing). Now when we were done with file copying , the memory that jumped from 30 to 52 is still staying at 52 .
So my question is that will RE0 memory stay there for long time ? (chances are it may increase from 52 to 100 due to some routing changes or something else) Or it can revert to previous value of 30?
If we wan to bring back Memory to its original value of 30 can we do this?
Further can we check from logs / commands what caused the memory to go high.
