Hi Bety, a problem like this was reported on IMQ mailling list a couple
of weeks ago. It is still pending review but it must be somehow related
to iptraf. :-|
I''m sorry for not being able to give you some "positive"
advice on it
for now.
Tks for reporting this issue. If you need assistance feel free to write
me privately or to join our list at www.linuximq.net
Cheers
Andre
