ARP requests for 127.2.0.1

Our GTM (BIG-IP 11.4.1 Build 635.0 HF2) is constantly—several times a second—sending out ARP requests out the mgmt interface for the IP address 127.2.0.1 with a source address of 127.2.0.2. For example:

2014-11-26 11:59:44.543142 00:01:d7:d5:2c:01 -> ff:ff:ff:ff:ff:ff ARP Who has 127.2.0.1?  Tell 127.2.0.2
2014-11-26 11:59:44.543149 00:01:d7:d5:2c:01 -> ff:ff:ff:ff:ff:ff ARP Who has 127.2.0.1?  Tell 127.2.0.2
2014-11-26 11:59:45.543200 00:01:d7:d5:2c:01 -> ff:ff:ff:ff:ff:ff ARP Who has 127.2.0.1?  Tell 127.2.0.2
2014-11-26 11:59:45.543205 00:01:d7:d5:2c:01 -> ff:ff:ff:ff:ff:ff ARP Who has 127.2.0.1?  Tell 127.2.0.2
2014-11-26 11:59:46.543134 00:01:d7:d5:2c:01 -> ff:ff:ff:ff:ff:ff ARP Who has 127.2.0.1?  Tell 127.2.0.2
2014-11-26 11:59:46.543140 00:01:d7:d5:2c:01 -> ff:ff:ff:ff:ff:ff ARP Who has 127.2.0.1?  Tell 127.2.0.2

Does anyone know why this is happening or how I can make it stop?
