No functional impact, these are not valid DDM alarms or warnings.
i2000 or i4000 series appliances with DDM enabled and a reboot or restart of the pfmand daemon
Ignore DDM errors that clear right away after powerup or pfmand restart.
During DDM initialization clear any alarms or warnings cached in the hardware registers.
