snmpd fails to start because it tries to bind a port twice

In Alpine Edge, snmpd fails to start, because it tries to bind the port twice. I attached a strace output which were generated by starting snmpd in the terminal:

$ strace -o snmptrace snmpd -Le

I think the relevant lines are 2163 and 2258

[2163]   bind(9, {sa_family=AF_INET, sin_port=htons(161), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
...
[2258]   bind(8, {sa_family=AF_INET, sin_port=htons(161), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 EADDRINUSE (Address in use)

Seems not consistent to me. I attached my config, too.
