      Description

      If you have 2 nodes with a given IP address, and then delete one (for example, because you're in the middle of migrating to a new provisioning requisition setup), then all new snmp trap events will not be connected to that node until OpenNMS is restarted.

      @jesse suggests this may be due to issues with a cache that is only rebuilt on restart:

      hmm, yeah I see how it could happen, it only stores a single entry for (location, ip address), so if there are duplicates, and then one is removed, the cache won't have any entries for that address until it is rebuilt, which only happens at startup
