Actually, that's still not enough information.  You're only giving
snapshots, to track the problem -- you need to be a little more active.
top is only good for tracking what's using alot of memory or CPU
-- so long as someone's watching the terminal.

What is the full 'command line' option for sendmail when this happens
(try ps auxw ;)?  

Is there only one instance of sendmail being run when this happens?

What entries, if any are being placed in the log file?

If you do a netstat -an, how many connections do you see either
in the ESTABLISHED or FIN_WAIT state to port 25?

If you do 'nc <box> 25' (or use telnet if netcat isn't installed) what
response do you get?

Often following those steps will give you information on where
it's failing.

Again, how does your mailing list software handle it.  If it is
connecting to SMTP rather than calling sendmail directly it could
easily cause this on it's own.

Gotcha, no consulting for free egh -- not even to satisfy a geeks
share of curiosity?  :).
