Network Lag with Bonding


Greetings:

I am setting up a new mail relay and recently installed bonding to deal with redundancy issues. This is the 6th or 7th server I've done and all the others have been fine. However, this server is having network lag issues.

The box is not yet running any apps and is 99% (or >) idle. When connecting to the box via telnet or ssh, the initial conenction is fine, but over the course of a few minutes, as you enter commands, keystrokes get slower and slower, up to a minute between when the key is pressed and when the box reacts. Finally, the connection is dropped, but can be quickly re-established.

Initially, I thought it might be a com link/parity issue, but seeing as how it only occurs on this server, I don't think that's the issue. Next, I thought it might be somethign to do with arp tables or DNS (the IP was used for another server previously), but the arp cashe has been cleared several times, the box and the switch it is conencted to have been rebooted, and DNS has been flushed.

I'm baffled. The physical link is fine. The problem is non-existant when bonding is not enabled, and the cat-5 cable has been swapped several times.

Here's the config:

ifcfg-bond0
--------------
DEVICE=bond0
BOOTPROTO=none
BROADCAST=xxx.xxx.xxx.xxx
IPADDR=xxx.xxx.xxx.xxx
NETMASK=255.255.255.224
NETWORK=xxx.xxx.xxx.xxx
GATEWAY=xxx.xxx.xxx.xxx
ONBOOT=yes
USERCTL=no

ifcfg-eth0
------------
DEVICE=eth0
BOOTPROTO=none
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes

ifcfg-eth1
------------
DEVICE=eth1
BOOTPROTO=none
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes

modules.conf
-----------------
alias eth0 tg3
alias eth1 tg3
alias scsi_hostadapter cciss
