Subject: 16GB memory limit on amd64
From: Jingcheng Zhang <dio...@gmail.com>
To: golang-nuts <golang-nuts@googlegroups.com>
Content-Type: text/plain; charset=ISO-8859-1

Hello gophers,

I'm running a server written in Go. It serves a lot of concurrent
connections, perhaps many millions per process.
Currently I don't know how to measure the accurate memory size used,
and when the process will reach the 16GB memory limit and panics.
The "top" command shows 2574M on VIRT, and 100M on RES.
Will the process panics when "VIRT" reaches 16G ?
Are there any detailed docs on Go's memory usage?

Thanks.
