We have any apache web server with 16 GB RAM , memory consumed is around 14 GB, we only have apache running on it. It is using around 400 Mb for thread.
I dont see any other service talking memory. Bt even on restarting apache I still see > 12 Gb memory usage.
I had run top command & seen if there is any other process but, nothing is there.
What should be eating my memory..I only get the memory to normal after restarting my server
