Hello,

there could be a problem with MAC address clearing or spanning-tree instability. Can you post the output of the command ?

show spanning-tree vlan vlan-id

Manually prune any vlans you don't need to be passed on the trunk this takes up resources even if the vlans aren't being used . What does show proc cpu show , is this normal ? If so you might want to see if there any known bugs for memory leaks for the version you are using .
