The two problems that can be caused by many ARP requests and reply messages are if switching is slowed down by a lot of ARP request and reply messages, the switch may have to alter its MAC table a lot and the other one is the ARP request will overwhelm the entire subnet because it is transmitted as a broadcast.
What is ARP?Address Resolution Protocol is referred to as ARP. The system must translate an IP address into a MAC address before someone can ping an IP address to their local network. The user will need to use ARP to resolve the address in order to accomplish this.
There are some other problems that can be caused by many ARP request and reply messages are :
Because they focus all the traffic from the associated subnets, switches get overloaded.All nodes on the local network must process each and every ARP request message.ARP reply messages have a huge payload because of the 48-bit MAC address and 32-bit IP address that they include, which could cause the network to become overloaded.To get more information about ARP :

Compare with datagram and virtual circuit packet switching networks. what are the differences and what are the advantages and disadvantages?
Datagram packet switching networks and virtual circuit packet switching networks are two different types of packet switching networks. Both have their own set of advantages and disadvantages.
Datagram packet switching networks are more flexible because each packet can be routed independently. This means that if one packet is lost, the others can still be delivered. However, this flexibility comes at a cost - datagram packet switching networks are less efficient because each packet has to be processed individually.
Virtual circuit packet switching networks are more efficient because the route for each packet is determined in advance. This means that the packets can be routed more quickly and efficiently. However, this comes at the cost of flexibility - if one packet is lost, the entire virtual circuit may need to be re-established.
