dhcpd: странные записи

[kirush]

Вчера нечайно уронил mpd4, переподнял, с этого момента в логи начались сыпаться:

Mar 10 11:44:32 accounter dhcpd: parse_option_buffer: malformed option dhcp.merit-dump (code 14): option length exceeds option buffer length.

С чем это может быть связано? В Гугле ничего понятного не нашел.

 

tcpdump на этот пакет говорит:
