option 82 logging error

[Marc Perea]

Hello,
I've set some logging up to write option 82 info to our syslog with the following in our dhcpd.conf:

log(info, concat("agent.circuit-id = ", option agent.circuit-id));

and we sometimes get errors in the logs that looks like:

Oct 15 12:40:57 isg-dhcp dhcpd: [ID 702911 daemon.error] parse_option_buffer: option <unknown> (808464737:50) larger than buffer.

I edited the IPs, but otherwise does anyone know why this is happening or what's going on here? Thanks.
