network crash and one general dhcpd question
today was the fourth time that the network on my rh9 box crashed. From one to the other second is no network transfer possible - even for other boxes in my network.
The redhat box runs several servers (httpd, dhcpd, openldap, samba).
I alway found tons of lines like following in /var/log/messages after the network crashed:
>> Jan 5 15:42:19 localhost kernel: eth0: Tx timed out (0000), is buffer full?
What does this mean, and where could I search?
Another thing are dhcps-messages in the same logfile. They appear every five minutes per box in my network and look like the following:
>> Jan 5 11:16:08 localhost dhcpd: DHCPREQUEST for 192.168.123.154 from 08:00:46:bd:7e:8a (DSA1) via eth0
>> Jan 5 11:16:08 localhost dhcpd: DHCPACK on 192.168.123.154 to 08:00:46:bd:7e:8a (DSA1) via eth0
>> Jan 5 11:16:20 localhost dhcpd: if IN A DSA1.d-s-a.local rrset doesn't exist add 300 IN A DSA1.d-s-a.local 192.168.123.154: timed out.
Is this normal? (I even don't know exactly, what they mean... Especially the last one...
Thanks a lot!
