Pump deconfigures interfaces when it thinks it is unable to renew leases, dispite being re-granted the IP address by the DHCP server. From /var/log/messages on local machine running pump: Apr 18 11:31:03 brick pumpd[476]: configured interface eth0 Apr 18 12:15:20 brick pumpd[476]: failed to renew lease for device eth0 Apr 18 13:49:16 brick pumpd[476]: configured interface eth0 Apr 18 14:08:05 brick pumpd[476]: failed to renew lease for device eth0 Apr 18 14:08:58 brick pumpd[476]: configured interface eth0 (each re-configuration of the interface is a result of a /sbin/ifup eth0) The logs on the DHCP server (RH6.2) indicates that it is being re-granted the same IP address successfully.

The problem can become quite severe. Here are the logs from this morning: Apr 19 09:47:04 brick pumpd[476]: configured interface eth0 Apr 19 09:48:42 brick pumpd[476]: failed to renew lease for device eth0 Apr 19 09:49:17 brick pumpd[476]: configured interface eth0 Apr 19 09:49:54 brick pumpd[476]: failed to renew lease for device eth0 Apr 19 09:49:58 brick pumpd[476]: configured interface eth0 I will post a log of the dhcp network traffic later today.
