linux still dying;potential errors

[Littlefield, Tyler]

Hello list,
I'm still getting a dead network at random.
Here is what came up in syslog about the time the connection died:
May 18 15:11:43 tysdomain dhclient: DHCPREQUEST on eth0 to 192.168.1.1 port 67
May 18 15:11:43 tysdomain dhclient: DHCPNAK from 192.168.1.1
May 18 15:11:43 tysdomain dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 7
May 18 15:11:44 tysdomain dhclient: DHCPOFFER from 192.168.1.1 graphic 581 May 18 15:11:44 tysdomain dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port
67
May 18 15:11:44 tysdomain dhclient: DHCPACK from 192.168.1.1
May 18 15:11:44 tysdomain dhclient: bound to 192.168.1.101 -- renewal in 43200 seconds. 
Does this tell anyone anything?
Thanks,
