Could be - there were some changes in the format of those entries around the
3.0 release so that the 'freshness date' actually worked.  Could have been
some bad & stuck data.  Not the problem I would have expected that to cause
but who knows?

Deleting the cache CAN NOT hurt and isn't a bad idea...  in fact the make
install script does delete this automatically.  During startup, if the file
is old (IIRC 4 days), ntop deletes it also.
