high mem

any ideas?  i like to keep pycharm open since i use it every day, but if it is doing something when i have no projects open then i would rather close it.

The Java virtual machine will allocate a certain amount of memory, up to the limit specified in the configuration file, but will not release it to the operating system even if the application is no longer using it. PyCharm is not doing anything when it doesn't have any projects open, but the memory will remain allocated.
