hi, can you provide software versions, I will check if there is any software bugs on this.
otherwise I recommend to open a cisco TAC case for the device.
1. %MCAST-6-L2_HASH_BUCKET_COLLISION: Failure installing (G,C)->index: ([enet],[dec])->[hex] Protocol :[dec] Error:[dec]
This message indicates that a L2 entry could not be installed in the hardware because there is not enough space in the hash bucket. Multicast packets will be flooded on the incoming VLAN because the Layer 2 entry installation failed.
Recommended Action: No action is required.
Related documents- No specific documents apply to this error message.
2. %MCAST-6-L2_HASH_BUCKET_COLLISION: Failure installing (G,C)->index: ([enet],[dec])->[hex] Protocol :[dec] Error:[dec]
This message indicates that a Layer 2 entry could not be installed in the hardware because there is not enough space in the hash bucket. Multicast packets will be flooded on the incoming VLAN because the Layer 2 entry installation failed.
Recommended Action: No action is required. Note In later 12.1 E releases, the SYSTEM_CONTROLLER facility name replaces the MISTRAL facility name. For example, MISTRAL-3-ERROR becomes SYSTEM_CONTROLLER-3-ERROR. Both messages indicate the same system condition. Note An "SP" between the facility and the severity level (for example, MISTRAL-SP-3-ERROR) indicates that the condition is coming from the Mistral ASIC on the supervisor engine. If nothing appears between the facility and the severity level (for example, MISTRAL-3-ERROR), the condition is coming from the Mistral ASIC on the MSFC.
HTH, rate if this helps
