Chrome SBOX_Fatal_Memory_Exceeded

[probablydumb]

Hello everyone so i was chilling on a livestream on youtube with 10k viewers and all of a sudden someone started spamming weird characters over and over in chat and my tab crashed giving me the memory exceeded error after that i reopened the livestream and i crashed again,and again,and again and all of a sudden it stopped.After 5 minutes someone typed in chat that the guy spamming was spamming because he wanted to crash mobile users by filling up their memory.The guy started spamming again and this time i didn’t crash.Is the error caused by the spammer or a problem on my end?

This is an error caused by the spammer. It mostly affects lower end phones with less RAM. Like my phone has 6GB of RAM and it would prob also fall victim. But phones with 8GB or higher will likely not have this problem. 

 

If you would like me to elaborate on how this bug works, just reply asking for an elaboration if you are curious. 
(the exact same bug actually existed in minecraft and was used against others to crash game clients  and prevent them from joining specific servers. Although in minecraft's case it wasn't a memory error, but rather a network bandwidth error. But the exact same underlying problem is being exploited in both.)

But how this bug still work even though i have 32 GB of RAM? It doesn't fully crash my chrome it just crashes that one tab and i have to refresh it. Does chrome have tabs capped at a certain RAM usage or?

Ohhh wait, I thought u were also a mobile user and I was really surprised phones existed with more than 20GB of RAM, I do not follow the mobile tech space at all but it would have been news to me. Do you know if you have a system page file enabled on your PC? Systems with more than 16GB of RAM typically do not have a page file, as it is not necessary. IIRC there is a limit of how much memory a single tab can use before it starts moving stuff to a page file, but if there isn't a page file, I guess the tab crashes because it exceeded the memory allocation?
