Hi All,
	When I rebooted the machine, the server is working fine.  I have also 
noticed that when the recent module behaves unexpectedly, it just adds 
one 'last_pkts' entry to the file /proc/net/ipt_recent/DEFAULT for each 
host even though there should be more entries (i.e, if the hosts are 
connecting for more than one time).


Has anybody experienced it?. So this should be a bug???
