[ HELPFUL TIP ] Slow HDD + 12Gb RAM = system crash

per the op...
You will need to add them to your rc.local file

Code: [Select]

gksu leafpad /etc/rc.localand insert them just above the exit 0

Code: [Select]

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytesto rc.local fixed that.

Weird, when i type this in a terminal i get an access denied error by bash. Why is that?

Hello,

I've got a bunch of old HDDs – ATA/SATA, 80-512 GB, Seagate, Maxtor, Samsung – a small zoo
Gigabyte P43T + E8400 + 12GB -  that's desktop the only one with IDE port nearby.

So I tried to do some cleaning = moving tons of files from one HDD to another + zip some directories.
And 2.2 started to crash, even no mouse movement.
It could work for 10 minutes or died almost immediately – unpredictable.

Tried acpi=off, noapic, nolapic & etc with no success.


In the end I've found out this article:
http://unix.stackexchange.com/questions/107703/why-is-my-pc-freezing-while-im-copying-a-file-to-a-pendrive

Seems lot of RAM + slow HDD is a common bug.

Code: [Select]

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytesto rc.local fixed that.

Just type it here in case anybody else rush into.
