Opennms，新节点无法识别snmp

Question

升级到版本22.0.2后，新节点无法识别snmp。

output.log:

Exception in thread "DefaultUDPTransportMapping_0.0.0.0/0" java.lang.RuntimeException: java.net.SocketException: Socket closed

这是我重新扫描节点时tcpdump的输出：

root@opennms:/etc/opennms# tcpdump -i any -nn port snmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on any, link-type LINUX_SLL (Linux cooked), capture size 262144 bytes
