Description of problem:
When I make an infinite cycle for allocating memory with malloc function.
The first time when i start the program After the memory is finished the
system Terminates the process, But if i start 2 processes simultaneously
the system almost allways hangs completely. The interesting thing is that
this happens if I use the default RedHat kernel shiped with RH7.2 (2.4.7).
If I try with 2.4.14 this does not happen. Even regular user can crash the
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Write this code
2.Compile the program
3. Run the program. If it does not hang from the first time. Start 2
processes SIMULTANEOUSLY. It will hang for at most 4 tryes.
Actual Results: The system is Completely Hanged. I can not change the
console with Alt-F1-6. I can do nothing from the keyboard. I do not know
about the network but may be it hangs too.
Expected Results: Instead of this the system should terminate the
processes as it had done the first time when i Tryed this
Nothing Appears on the console.
My system is RH7.2 Default instalation. No patches applyed.
Intel Celeron 433
163 MB RAM
But this works and on P3 733, 256 MB RAM, I815 chipset. The same
Distrubution with all relevant patches applyed only the kernel is default.
I have and kernel 2.4.14 compiled too and this is not happening with it.
Even regular user can crash the system.
The 2.4.9 kernel errata should have this fixed.
