I have a CentOS 7 server that is running out of memory
How do you know that? Give a specific symptom.
This was brought to my attention because one program was killed by the kernel to free memory and another program failed because it was unable to allocate enough memory.
Running "free -h" gives me this: total used free shared buff/cache available Mem: 3.4G 2.4G 123M 5.9M
This is such a common misunderstanding that it has its own web site:
https://www.linuxatemyram.com/
Right, and that website says that you should look at the "available" number in the results from "free", which I what I was referencing. They say that a healthy system should have at least 20% of the memory available. Mine was down to 17% in what I posted in my email and it was at about 8% when I rebooted yesterday.
