Memory management in Kernel 2.4.x
Hello,
Quoted 6 lines
Unfortunately, the memory management of kernel 2.4.x didn't get better until today. It is very easy to make a machine dead. Take the following script:

The result with kernel 2.4.19pre8ac4:
What about results with latest -aa kernels?
I'm writing this letter while running your killer-test ;) My machine is perfectly responsive.
$ uname -a Linux localhost 2.4.19-pre6vm33 #2 Sat Apr 13 00:56:55 MSD 2002 i686 unknown This is vanilla 2.4.19-pre6 + vm33 from Andrea Arcangelly.
Funny stats:
bash-2.05$ free
total used free shared buffers cached Mem: 516496 512804 3692 0 2080 10064 -/+ buffers/cache: 500660 15836
Swap: 1028120 1028120 0
I'm running X, netscape, mutt, top, 5 xterms, web, mysql, ftp, samba etc. Lots of "0-order allocation failed" in the log. Anyway it is usable! The good thing is VM is killing right process most of the time:
VM: killing process memory-killer
Netscape got killed. Big deal, I can start it again and it works...
P.S. Running it already for 20 minutes.
