Description of problem:
When the CPU is running at 100%, the network stops working.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install redhat 7.3 (probably a kernel issue)
2.Install ISA (ne.o) network card
3.Run a task (as root) that takes 100% of your CPU.
Actual Results: Network stops functioning...
Ping eventualy times out and says host not reachable.
Expected Results: Network should work properly.
2.4.18-4smp #1 SMP i686 (also occued with 2.4.18-3smp)
SMP system with NE.o network card.
I tested the network by running this application (as root) over an SSH
I would expect the progress ouptut to show up as the application ran, but
instead all the output shows up at the end when the application has finished.
float x=3.14159, y=9.51413, z=1.23567;
I also ran:
ping 126.96.36.199 > pingOutput 2>&1 &
while the application as running and the pingOutput file looked like this:
[paul@heatman paul]$ cat pingOutput
