Per Cisco, "overruns occur when the network interface card is overwhelmed and cannot buffer received information before more needs to be sent."
You have only 30 overruns. I have 30 of them a day and Cisco tells me not to worry.
The strange thing with your stats is that you have 0 input errors whereas everytime my overrun increases my input errors count increases by the same number.
If I were you, I would worry more about the no buffer count:
"no buffer, the PIX Firewall is out of memory or slowed down due to heavy traffic and cannot keep up with the received data."

Hi,
i make to show interface and i saw :
interface gb-ethernet1 "DMZ-Slot:2" is up, line protocol is up
Hardware is i82543 rev02 gigabit ethernet, address is 0003.470d.1d87
IP address 192.168.1.33, subnet mask 255.255.255.248
MTU 1500 bytes, BW 1 Gbit full duplex
3341141891 packets input, 13144045776340 bytes, 8518002 no buffer
Received 7621 broadcasts, 0 runts, 0 giants
0 input errors, 0 CRC, 0 frame, 30 overrun, 0 ignored, 0 abort
3694112040 packets output, 2509048378726 bytes, 0 underruns
input queue (curr/max blocks): hardware (255/255) software (0/0)
output queue (curr/max blocks): hardware (0/21) software (0/0)
and i don't know the cause of the 30 overrun, because i didn't these errors in the port switch.
Can someone help me ?
Thanks
