I've been getting a lot of this error on one of my FreeBSD 6.2 boxes. I have
5 other servers running the same configurations as this one and none of them
is giving me the error.
The only different between this and the other servers is AMD on this one and
Intel on the rest.
The repeated errors given were:
vr0: receive error (0406) overflow
vr0: rx error (09): FIFO overflow
vr0: rx error (09): FIFO overflow
vr0: receive error (0407) overflow
vr0: rx error (09): FIFO overflow
vr0: receive error (0407) overflow
vr0: receive error (0404) overflow
vr0: rx error (09): FIFO overflow
vr0: receive error (0404) overflow
vr0: rx error (09): FIFO overflow
vr0: receive error (0404) overflow
vr0: rx error (09): FIFO overflow
vr0: rx error (09): FIFO overflow
vr0: receive error (0407) overflow
vr0: rx error (09): FIFO overflow

................
This server is acting as socks5 proxy server connecting to 40-80 users,
which will connect to more than 8000-11000 peers.
All other servers can push close to 85mbit/sec but this one can only go to a
max of 25mbit.
Anyone? Is this configuration or hardware problem?
Thanks
