Dear All

This may be offtopic but here goes ...

I've an old box resurected as a qmail server for a small office.  It
only has 16 meg of ram, but seems to cope quite well.  Until this
morning! (log entries below):

The machine appears to have been flood via Ident requests - This smells
of a DOS via Identd to me ....

Is not running identd (its run as a daemon from /etc/rc.d/) for a smtp
box going to cause problems ?

Has anyone else seen such issues on a low memory qmail server / redhat
6.2 box ?

I have no other problems with other redhat / qmail boxes of different
vintages (although they all have more ram). 

Any clues greatfully recieved.
