Yes, the first thnig I did was to I check  both of them. In fact, there were
a lot of  messages like :
-----------------------
Jan 18 10:40:15 pluto kernel: ip_conntrack: table full, dropping packet.
Jan 18 10:40:15 pluto last message repeated 9 times
Jan 18 10:40:22 pluto kernel: NET: 4 messages suppressed.
Jan 18 10:40:22 pluto kernel: ip_conntrack: table full, dropping packet.
-----------------------

but *mixing* with these messages, there were still some log of FTP
transactions from other workstation to this server. I mean after message of
"dropping packets" there were some other successful transactions for ftp.

Could it be some problem with iptables ?

Thanks,
