Asus RT-AC68U Ignoring duplicate dhcp-option 252

[RIleyrott]

I've had the RT-AC68U for about a month running Merlin 374.40 with very few problems, but lately have been getting the following messages in System Log:

I'm not running a proxy and can't figure out why this is happening as of late. I'm kind of a noob to all this and would appreciate some help. Thanks.

What do you have in /jffs/scripts/ and /jffs/configs/ ?

 

[RIleyrott]

How do I view the /jffs/scripts and /jffs/configs folders?

ETA: I used WinSCP to login to the router and found the /jffs/scripts folder. It contained the following:

dnsmasq.conf.add
dhcp-option=252, "n"
dhcp-option=252, "n"

Note: Somehow, this command was entered twice, so I deleted the 2nd entry and it seems to be OK now.
(I used this command because a Win7 computer was hammering the router with dhcp-requests)

BTW: There was nothing in the /jffs/configs folder.
