>Description:
We have a server here which rl0 driver (the ethernet card is a Realtek 8139 10/100BaseTX) 
freezes from time to time.
It seems to be related to both bugs #12394 and #9537.
We get "no free buffer space avalaible" when trying to 
ping another computer and the only way to fix the problem is to restart 
the rl0 driver by doing a "ifconfig rl0 down; ifconfig rl0 up".
We think it might come from an overload of the server due to the number 
of emails it sends to the administrators for system administration.
>How-To-Repeat:
No real 100% sure way. Just let the server run and send tons of emails.
The driver should stop at some point.
>Fix:
Restart the driver :
"ifconfig rl0 down; ifconfig rl0 up"
