Rahul, send us the output of "free -h". For us to help, we need to see what
you're seeing. You keep asking us to help you "clean up" or "free" the RAM,
but: we don't even know if it's actually in use.
For example:
$ free -h
total used free shared buff/cache available
Mem: 1.9G 419M 714M 132K 835M 1.3G
Swap: 975M 96M 879M
This shows I have 1.9GB of RAM on this VM. And "only" 714 M free -- but look at
the far-right column, where I have 1.3 GB available. The implication here is
that I've only got around 600MB of memory that's in use and not free for other
applications.

Subject: [lug:18665] Re: Ram memory not freed after executing python script on
ubuntu system
@Daniel Eggleston You may be right as i was wrtiting a very big numpy array
file in python. But due to some issues i had to terminate the execution in
between. The size if ram may be due to that processed numpy array that needs to
be written at the end of the script. I was monitoring RAM and other resources
from System Monitor in ubuntu. Yes size of swap reduced from 14 gb to 8 gb. May
i know if the file buffers are the caise of this huge usage of RAM. How to
clean this unused wasted space of the RAM. Please help

I am having a Ubuntu system which has 125 Gb of RAM. I executed few python
scripts on that system. Those scripts uses numpy arrays and pandas. Now
execution was over but still 50 gb of RAM and 2 Gb cache and 8.4 Gb of swap is
occupied. At this moment nothing is running on the system. I have googled it.
Most of th result shows that python garbage collector is poor in performance. I
want this memory to be cleaned and re claim. One of the easiest way is to
restart the system but i dont want to restart i want a way to do this when the
system is up and running. Kindly tell me how to do this. Thanks
