Odd log entries - xinetd

[ABrady <kcsmart kc rr com>]

Anybody seen these entries and/or can tell me what they mean? They've
just started happening in the last few days and I just noticed how many
there are:

These entries, from a little earlier than the above, would lead me to
believe something more is amiss:

Aug 17 08:41:10 alan rpc.statd[1298]: gethostbyname error for

signal: 11 (Segmentation fault)

Are these signs that I have something to worry about?
