Today I found following "nice" bug: 134.130.48.70 0x1 0x2 00:E0:98:AD:01:97 * eth0 134.130.48.157 0x1 0x2 00:10:4B:4D:01:97 * eth0 134.130.48.157 0x1 0x2 00:10:4B:45:86:6C * eth0 These three entries appeared near the end of the output and had no lines between them. Notice how the second MAC is composed from the other two. The first and last entry is correct. If my database and script etc. work correct, this (wrong) second combination occured at least five times, but only one of them showed up today. Where is the bug? What should I do to avoid this?
