NM memory usage increases after a large number of IP addresses are added and then deleted
A test case is as follows: Add 700 IP addresses on the NIC with the ip command, and then delete the IP addresses. The following issues were found:
- After other IP addresses are deleted, the interface has only one dynamic IPv4 address. When the DHCP lease is renewed on the interface, the deleted IP addresses are added back by the NM.
- The memory usage of the U2000 increases. Repeated execution of this test case triggers OOM. In this case, the NM occupies more than 1.5 GB memory.
