Really? I've never heard anyone mention this and I've followed Go for years.

Yeah, it mostly happens when you have a server which runs an abnormally large task or payload, causes the heap to grow, and does it in a way that Go can't release the memory back to the OS due to heap fragmentation.

I haven't looked at this for a while but I believe it's still an issue.
