Comment From: aarzilli

Are we really sure that this is just an OOM and nothing else? I get it for growslice and newarray, but all those newobject?

Comment From: adonovan

Presumably if a windows process is running out of memory then any allocation site could be culpable for causing it to exceed the limit with a probably equal to its fraction of the total allocation rate. So we should expect to see calls to newobject, even if the object is small, if they are frequently allocated. Most of the sites above are in the parser and type checker, which are hot allocators, so this seems reasonable to me.

But I'm not a runtime expert. @prattmic is, though.

Comment From: prattmic

@aarzilli It is hard to be sure, but that is the leading theory. On Windows, VirtualAlloc actually reserves physical memory. i.e., if the system is out of memory, it will actually fail. On most (all?) Unixes, mmap doesn't actually reserve physical memory, so it basically never fails. (Actually touching the page will make the OS find physical memory during page fault handling. If it can't, then the kernel invokes the OOM-killer to kill something to free memory. If it kills us, no telemetry report...).

Since this has only been seen on Windows, the theory is that we're seeing system OOM conditions.

The runtime's memory allocator will try to serve any allocation out of existing mappings, but if it does not have one it will go to the OS for more pages. Thus any allocation may trigger going to the OS. I think the probability distribution would approximately match alloc_bytes in a heap profile. i.e., the more bytes allocated, the more likely you need to go to the OS. That could be fewer big allocations, or more small allocations.

Comment From: aarzilli

I can't prove anything but the stack trace that I saw for delve (https://github.com/go-delve/delve/issues/4073) isn't even on a path that does a lot of allocations. Of course it could be that we're leaking somewhere else and that just happens to be unlucky but it looks odd to me. Not that I have any suggestions, btw.
