Why did you do that manually and not let the network scripts do their
job?

You hopefully have seen that things changed here: not only the IP
address, but too the subnet mask changed from 255.255.248.0 to
255.255.255.0. Said that your next posting shows in ifcfg-eth0
"NETMASK=255.255.248.0" which does not reflect this change.
