>Description:
After a reboot the system seems to run fine at first. After about 5 mins of heavy transfer or about ~2 hours idle/remote access (10mb/s) the speeds start to go rapidly and drop to below 12k/s with a 100mbit nic or to 120k/s w/ a 10mbit nic (no i didn't mess the numbers up) (The 10baseT nic works fine when the FBSD machine is on the receiving end). After that the machine almost cannot me accessed remotely, and it feels like there is severe lag. Pings go up to ~50ms local but there's no packet loss. It's not EM either since I moved the machine about 10 times trying different cable also. The machine still updates regularly however (cvsup) and seems to have no problem.
>How-To-Repeat:
Reboot and either wait for about 5 minutes under heavy traffic or wait 2 hours when idle.
