Re: [go-nuts] Where is my memory in Linux?

Thank you for your reply.

No, this app doesn't use cgo. It's a pure Go application. Another go 
application on this VM used cgo. But it also should not launch the 
subprocesses.

[go-nuts] Where is my memory in Linux?

[Zhang Rui]

Hello gophers, 

I have a VM on Linode.com. OS is Cent OS 6.8 and kernel 
is 4.14.12-x86_64-linode92. It has 1 CPU core and 2G RAM.
A Go application is running on this VM.
Free memory on this VM is 490M (with buffer and cache), The RSS value of 
this Go application is only 12M. After I kill this Go app, free memory will 
increase to 950M. I have called Debug.FreeOSMemory() in this Go app every 
minute.
Sometimes, free memory will be decreased to 0 and this Go app will be 
killed by oom-killer. Does anyone know where is my memory?
