The compute node's service processor has a limited amount of memory. If you are unable to create a new configuration because the service processor ran out of memory, delete unused configurations using this procedure.
# ldm list-config factory-default V_B4_4_1_20150825155356 CM_3S3T_1S1T_082820151531 CM_30C2560G_18C1536G_082820151559 CM_1S1T_6C512G_082820151618 [current]
It is safe to remove any configuration that contains the string CM_ or _ML, as long as it is not marked [current] or [next poweron].
For example:
# ldm remove-spconfig CM_3S3T_1S1T_082820151531
