High Memory Usage?

Hello I keep having issues with high memory usage .
Since the start of this week memory usage would climb to 100% when having pycharm and firefox opened together , and pycharm gets automatically killed.

The processes barely add up to 20% of total memory. but system monitor says 60% of my memory is used. Am I missing something here?

This hints that PyCharm consumes the most memory at that time.

Hm, yes I hadn’t created a swap partition due to disk space limitations . I did now and it seems that it actually helps . I will come back tomorrow if everything is fine to mark this as the solution.
