Intel e1000 drivers have been a continual source of pain for me under
CentOS5. I ended up rebuilding a box as FreeBSD to get past the problem
as the BSD driver was more stable. Didn't matter which version of the
intel drivers I used, as often as 5x a day the network card would jam up
its TX buffers.

Hi there,
I have had severe problems with CentOS 6.x networking on machines that
run CentOS 5.x just fine. After much headache and pain, the problem
for me boiled down to crappy network drivers included with CentOS/RHEL
6.x. I have found updating the drivers to be very simple and it has
always fixed my problems. The hardware I'm referring to has been using
Intel e1000 or Intel e1000e drivers. So, without knowing a whole lot
about your specific problem, I'm suggesting to try updating your
underlying drivers.
For example:
#e1000
rpm -Uvh
http://ftp.osuosl.org/pub/elrepo/elrepo/el6/x86_64/RPMS/kmod-e1000-8.0.35-1.el6.elrepo.x86_64.rpm
#e1000e
rpm -Uvh
http://ftp.osuosl.org/pub/elrepo/elrepo/el6/x86_64/RPMS/kmod-e1000e-1.11.3-1.el6.elrepo.x86_64.rpm
hope this helps,
Chris
