Hi,

What could be reasons of having high send-q and recv-q. The server has a
NC7781 Gigabit Server Adapter and running RH 2.1 ES.

# netstat
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 10132 23568 xml.nowhere.cc:rsync 129.219.32.65:1258
ESTABLISHED


The number of collisions is also very high according to the ifconfig:

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:170471326 errors:0 dropped:0 overruns:0 frame:0
TX packets:15307480 errors:0 dropped:0 overruns:0 carrier:1200486
collisions:1277686 txqueuelen:100
RX bytes:496808930 (473.7 Mb) TX bytes:3048463795 (2907.2 Mb)
Interrupt:5 Base address:0x3000


Any ideas on how I can go about troubleshooting this? What are some some of the configurations file that I should look at?


Thanks.
Sarah

Collisions are a physical problem caused typically caused by high traffic volume on a given segment of the network. Try further segmenting your network. How you go about this depends greatly on how you have your network set up. If you need help with that, or if this doesn't apply, please post some more information--e.g., about your network--here.

Hi Sarah,

Check your NIC speed,duplex,autoneg settings....
