But same was working for short data.. if ran for more number of scans then it is throwing an error

[bjorn3]

Maximum call stack size exceeded

That is a browser limitation. It may be possible to rewrite the profile loader to avoid this limitation. I'm not familiar with the actual code of speedscope though.

OK what is maximum size it supported now? and if want to change where I can change ?

OK what is maximum size it supported now?

Depends on the browser.

and if want to change where I can change ?

According to https://stackoverflow.com/questions/35380984/increasing-stack-size-in-browsers you can do something like

ulimit -c unlimited
chrome-browser --js-flags="--stack-size 2048"

(ignore the ulimit -c unlimited if you are on windows)

You will likely need to quit chrome entirely before doing this. In addition it is not a persistent option. Even this may still not work depending on how deep speedscope recurses when loading your profile.

Hi @vinsjr!

It's difficult to help without having the file that isn't loading. If you can provide the file that isn't loading, it may be possible to debug your issue & resolve. Without the file, I'm afraid I can't do much to help.

I'm pretty sure this specific stack overflow would be fixed by #438 (the method names and line number match this).
