Hi all,

The PF_RING seems not to work smoothly in CentOS 5.
Several day before, I patched the kernel 2.6.25.3 and
installed the PF_RING-patched kernel in my CentOS5.
Based on the PF_RING, I developed my program to capture
the network packages. I wished it can work until the
machine power is off. Unforturnately, no matter how to
adjust my program, whole system can not run more than
48 hours. Finally, whole system crashed and syslogd said
it found the following kernel output.

I have contacted CentOS people, but they said they had not
met the same problem in their operating system before.

I googled the internet and found similar bug occurred in Ubuntu
on the same hardware platform: Dell poweredge. However, the
fixing has to patch current kernel source code.

https://bugs.launchpad.net/ubuntu/hardy/+source/linux/+bug/214814

Also, I don't know what kernel they used. I downloaded the kernel
source codes from www.kernel.org and patched it with PF_RING. Then,
I setup the pathed kernel to run CentOS 5.

I would like to know whether I can avoid the bug if I used the
original CentOS kernel code, not the one from www.kernel.org.

Are there anyone who meet the similar trouble?

Thanks a lot.

CentOS 5 uses kernel 2.6.18-xx ... If this PF_RING thing requires a
different kernel, I think a more accurate statement would be, PF_RING is
not supported on CentOS.
