V8 Embeded Application throws Exception randomly. [RangeError: Maximum call stack size exceeded]

[siam...@gmail.com]

Hi,

I am using V8 in an asp.net application. I wrote some c++ code to expose some  V8 functionality  to C# via PInvoke.  I create V8 Isolate object (in future we will use isolate pool for reuse.)  for every request and dispose end of the request. In our test environment I found sometimes V8 throws exception (RangeError: Maximum call stack size exceeded). I also verified their is no recursion in script. For that request V8 execute react, react-dom server and a simple script that has react view. In order to repro this I created a simple console app and ran it 10000 times but couldn't repro it. I also ran 200 thread simultaneously which created isolate object and ran script then dispose isolate but still not able to repro this. Do you guys any suggestion how can I dig into this and what is the configuration I am missing for my web application.

Thank you

Siam

Start V8 with `--abort_on_stack_or_string_length_overflow` (see
`v8::V8::SetFlagsFromString()`) and, if possible, run your application
in a debugger. The abort backtrace should hopefully yield some clues.

Reasons beyond simple recursion for a stack overflow are complex
regular expressions or (very) deeply nested source code.

If V8 somehow guesses the stack size wrong, you can correct it with
`--stack_size=<size in kb>`. Note that it tells V8 to _assume_ the
stack is this large, not _create_ a stack this large.

He Ben,

Thanks a lot for this information. Is there any way to get the current stack_size ?

Thank you

On Windows? https://docs.microsoft.com/en-us/windows/desktop/api/processthreadsapi/nf-processthreadsapi-getcurrentthreadstacklimits

If you mean V8's default value on your platform, `d8 --help` will print it.
