I can't find the device which is sending the ARP requests. The first three octets of the MAC address are 00ae13
. But they are not assigned to a known manufacturer.
Does anybody have a clue what kind of device this could be?

If you happen to use managed switch(es), you could log into your switch(es) and look into their forwarding table to see on what port of the switch is registered this mac address. You could then follow the trail up to its source.
The way to look at the forwarding table depends on the manufacturer of your switch(es). If your switch has a command line interface and you're familiar with terminal, try "show mac-address" (I know it to work on both my HP and Brocade switch). Else look at the Web GUI.
If your switch is not managed, or you don't have access to it, maybe you could find whose sending by capturing these arping packets on various places of your network: try sniffing the network using wireshark or tcpdump on suspicious VM, or on the physical network interface of your ESXi...
my 2 cents :)
