what triggers these?

["Kretzer, Jason R (Big Sandy)" <jason.kretzer () kctcs edu>]

Hello all,
 
Generally, what triggers these two alerts?
 
[**] [119:15:1] (http_inspect) OVERSIZE REQUEST-URI DIRECTORY [**]
 
and
 
[**] [1:1416:9] SNMP broadcast trap [**]
 
The first is coming from the outside world, the second is coming from a
network printer.  Are these anything to be really worried about?
 
thanks,
 
-Jason
