Symptom: The ASR1K CPP10 based platforms and ISR/CSR could generate a traceback while allocating a scheduling node before the resources are depleted. The failure adversely affects the current and subsequent configuration events. Conditions: If the BQS resource manager returns synchronously while after it has activated the scheduling node, it generates the following traceback after resuming processing of the same scheduling node to place the children in the tree and process the scheduling node rate. \ IF:GigabitEthernet0/0/1.463: cpp_qm_event__proc_parent_activate:8332 alloc_schedule FairQueue_0x40000adc: OBJ_H: (0) 0/0x440000adc P_OBJ_H 0x40000ad7 flags: 0x4006 state: 0xc05 w/16 children adding 16 chh ildren failed The failure gives a false alarm about resources outage. The traceback is caused by an erroneous logic when the scheduling node is already marked as ACTIVE before it is complete processed.
