Long connection pauses?

[Brian Chabot]

I've been pulling my hair out trying to figure soething out.

I have a relatively new machine that pauses for 20-120 seconds between 
SYN/ACK and issuing the banner on all TCP connections.  This has been 
verified by several other systems connecting and using both windows and 
Linux.

The machine is running Mandriva 2006, but so are three other machines on 
the network and none of them have this problem.  All the xinetd settings 
are identical, as are resolv.conf.  ps and top show nothing going on... 
just a pause of usually 20 seconds per tcp connection.

Anyone know where I might look to find out what is causing this? 

TIA,

Brian
