Testing this, its a 20Mb file. So quite largish. I’ll leave Brave open for an hour or 2, see what it shows. The pdf shows around 87k, I briefly saw 97k then it came down.

i dont know if the pdf is the problem, i see that is more like a trigger because the “RAM” goes to “browser”

Brave is multi threaded (feature from Chrome/Chromium), which is why you see a few processes in Windows task manager. Every extension, tab will create a new process and add memory usage.

Yes, thanks, even so, in Chrome that doesn’t happen, I’ve already tried it and it doesn’t get me up to 95% Ram usage, not even if I use brave normally without opening those documents, it makes me think that the documents are the problem, but it’s impossible, I’ve been using those same documents for at least 1 year without altering them at all, And they’ve never given me any problems

Re-check, its been about 4hrs (actually forgot about it). Its around the same value as before. Try testing in a clean Brave profile, or test in the latest Brave Beta, no extensions.

I read all above. If you are on Windows 10 w/current updates, then what worked for me was disabling all extensions. I have max allowed 8Gb of RAM on board and I bumped the virtual memory from 4 to 8Gb . No more crashes so far. It’s utilizing 6+ Gb of virtual memory on an SSD. This is a decade old laptop w/ AMD A10-4600M 4 threads.
