Comment 9 for bug 584048

Yesterday I saw another strange behavior.

I shutdown VM once a day to make a backup and I adjusted my scripts for the 1-10 min network freeze, but yesterday the network did not unfreeze at all. I restarted the machine and the network continued to be frozen! I had to physically power off the machine to unfreeze the network, as if something was kept somewhere in the network chip that resisted reboot. My machine is a HP DL380 G6

Network freeze is indeed not total. Not all IPs are blocked. It seems IPs that have no traffic at the time of the bridge operation are not blocked. So the freeze I am talking about above (the one that resisted the reboot) was not total. Some IPs were able to ping and connect and other no. And the situation was identical before and after reboot. Only after power off everything returned to normal state.

Hope it may help...
