[CentOS] ntop **ERROR** Queue of address '???' failed, code -1 [addr queue=4096/max=4097]

Hi all,

Running CentOS 4.2 with the following conditions:

[root@gatekeeper bin]# uname -srvmpi Linux 2.6.9-22.0.1.EL #1 Thu Oct 27 12:26:11 CDT 2005 i686 i686 i386

I've found the following error in syslog:
