    HDD indicator starts glowing constantly & PC freezes

    HDD indicator starts glowing constantly & PC freezes. The only running app is Firefox streaming an Youtube video. This does not happen all the time but when it happens the only way out is to use REISUB. Any ideas how to troubleshoot this ? I first noticed this issue while using Arch so I thought Arch's bleeding edge nature may be the cause so I installed Ubuntu but same thing is happening.

    Code:
    $ inxi -Fxz

    I have replaced Ubuntu 18.04 with Lubuntu 20.04 but the same thing is happening again. Is 4GB of ram too little ?

    It's not great. I wouldn't have gone for less than 8 for any of my machines for the last 10 years or so.

    Linux does handle being out of memory quite badly, and it would look like what you're describing, and hitting the swap hard would cause your activity light to be pegged on. There is work underway to improve that situation.

    There are tools you can use to monitor your memory usage and, if it is memory pressure that you're experiencing, ad blockers / script blockers might help to lower the memory footprint of your browser.

    There's something else at play there.

    While the above is true, the "toy" computer I'm using to post this also has only 4GB of RAM (DDR3L), coupled with an entry level Celeron. More often than not I have a few tabs open in Firefox AND Chromium, usually one of those is Youtube, plus a couple of bloated news feeds, plus Transmission, plus the heavyweight Java based JDownloader and occasionally one or two office files open... Sometimes I'm also running updates at the same time... Occasionally other random software as well... Believe it or not it works fine and smooth >99% of the time.

    In summary, I would be checking your Firefox addons before anything else.
