Hi There!

i would llike to know what this error message on my logs mean, also in particular with the "suppressed 719 times"  .  Could this affect memory usage?  if so, how do i clear memory usage on a switch

...trace the MAC address down gi1/43 and find the misconfigured device.

cheers,

True, found the mac address, and it seems that it was not a mac address with a valid vendor, problem is,, my switch's memory is still high, and not sure how to dump/clear the memory without rebooting

there is no way to clear or dump the memory. Only possible way is reboot the box.

Your memory allocation being high may be a consequnece of the (valid) configuration you are running on the 4500. Are you seeing any memory related errors in the system log? 

the only one is see every now and again is:  addto_mempool_pc_array(): overflow

this is also the memory allocations:
