DEC21140 is a FastEthernet controller, Unit 0 means FastEthernet0 being in
slot 0 of your 4700M, Excessive collisions mean that a packet was dropped
after trying to get on the medium for 15 times. The cause of this could be a
full segment, or a faulty device. It also is important to know whether you
use a hub or a switch. However according to your statement that it only
happens between 2 and 3 pm I assume that the cause is to be found in a
heavily loaded segment. Check your load during this time and try to decrease
it if so. It could also be worthwhile to check the status of your interface
(output errors, deferreds etc.)

DEC21140 Fast Ethernet controller error messages
Error Message
%DEC21140-5-COLL: [chars] excessive collisions
Explanation A Fast Ethernet packet was dropped because too many attempts
to transmit it were stopped by collisions. This
can be caused by a Fast Ethernet segment that is full to capacity or by
other equipment on the LAN malfunctioning.
Recommended Action No action is required.
