What should I do with this?

[Petrezselyem 6]

SYSERR: Dec 23 21:59:07 :: Process: FDWATCH: peer null in event: ident 20
SYSERR: Dec 23 21:59:09 :: Process: FDWATCH: peer null in event: ident 22
SYSERR: Dec 23 21:59:11 :: Process: FDWATCH: peer null in event: ident 23
SYSERR: Dec 23 21:59:12 :: Process: FDWATCH: peer null in event: ident 24

It happened after I put some weapons in my item_proto. I didn't do anything else, just that.
