Re: [v8-users] Cryptic out-of-memory error

V8 suffered from a virtual address space leak which was fixed and backmerged to 57 (https://bugs.chromium.org/p/v8/issues/detail?id=5945). Awesome it works for you now. On Thu, May 11, 2017 at 7:04 PM Andre Cunha wrote: > I have repeated the tests in V8 5.8.283.38,

Re: [v8-users] Cryptic out-of-memory error

I have repeated the tests in V8 5.8.283.38, and indeed the problem is gone. The amount of virtual memory remains stable over time. With regard to the cause of the problem, I managed to create a similar situation (increase in virtual memory consumption without increase in actual memory usage)

Re: [v8-users] Cryptic out-of-memory error

Thank you for the detailed bug report. I tried reproducing this on the latest version of V8, but couldn't observe the behavior you described. Have you considered updating to at least the latest stable version of V8? On Wed, May 10, 2017 at 7:50 PM Andre Cunha wrote:

Re: [v8-users] Cryptic out-of-memory error

I've managed to reproduce the problem using just V8's hello_world example (source code attached). I just added a loop around the creation and destruction of the Isolate (this is what happens in each cycle of my stress test). When I run the process and monitor it in "top", the RES column stays

Re: [v8-users] Cryptic out-of-memory error

@Michael Lippautz, I'll try adding a breakpoint if AllocateChunk returns NULL; hopefully, I'll get more information about the problem. @Jakob Kummerow, yes, I'm calling Isolate::Dispose() in every isolate after using it. I'll also observe the VIRT column and see if it shows any abnormality.

Re: [v8-users] Cryptic out-of-memory error

My guess would be an address space leak (should show up in the "VIRT" column of "top" on Linux). Are you calling "isolate->Dispose()" on any isolate you're done with? On Mon, May 8, 2017 at 4:01 PM, Michael Lippautz wrote: > V8 usually fails there if it cannot allocate a

Re: [v8-users] Cryptic out-of-memory error

V8 usually fails there if it cannot allocate a 512KiB page from the operating system/ You could try hooking in AllocateChunk [1] and see why it is returning NULL and trace back through the underlying calls. Best, Michael [1]:

[v8-users] Cryptic out-of-memory error

Hello, I have embedded v8 into a project for the company I work for, and during some stress tests, I've encountered a weird out-of-memory error. After considerable investigation, I still have no idea of what might be going on, so I'm reaching out to you in hope of some insight. So here is a
