nf_queue dropping error

I received a lot of this message from my kern.log but i do not really understand what it is refering to.

Oct 25 10:46:40 untangle kernel: [142482.879506] nf_queue: full at 1024 entries, dropping packets(s). Dropped: 472005
Oct 25 10:46:45 untangle kernel: [142490.615083] __ratelimit: 1556 messages suppressed


Do i need to be concern of this error?
