[cobalt-users] raq4 - sendmail rejecting connections - busy machine?

Hi,

I've had the following in my maillogs today:
Feb 23 16:32:51 www sendmail[459]: rejecting connections on daemon MTA: load average: 26 Feb 23 16:33:06 www sendmail[459]: rejecting connections on daemon MTA: load average: 27 Feb 23 16:33:21 www sendmail[459]: rejecting connections on daemon MTA: load average: 28 Feb 23 16:33:36 www sendmail[459]: rejecting connections on daemon MTA: load average: 29 Feb 23 16:33:51 www sendmail[459]: rejecting connections on daemon MTA: load average: 26 

This happened another day too.
Why would sendmail be rejecting connections? There have only been a few emails through the system and the active monitor gui says that the load on the cpu and mail has been low. 

I checked top for anything that suggests a problem:

 6:19pm  up 1 day, 56 min,  6 users,  load average: 0.60, 0.77, 0.87
140 processes: 138 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: 11.0% user,  8.9% system,  0.0% nice, 80.0% idle
Mem: 517368K av, 422796K used, 94572K free, 499944K shrd, 215716K buff Swap: 131448K av, 3332K used, 128116K free 42632K cached
Does that look okay to everyone? Busy or normal? What about the load average? 

And pstree saying this:

init-+-crond
    |-getty
    |-httpd---5*[httpd]
    |-httpd-+-77*[httpd]
    |       `-httpd---script.cgi
    |-inetd
    |-kflushd
    |-klogd
    |-kpiod
    |-kswapd
    |-kupdate
    |-lcdsleep
    |-mdrecoveryd
    |-named
    |-2*[portsentry]
    |-postmaster
    |-4*[raid1d]
    |-safe_mysqld---mysqld---mysqld---mysqld
    |-sendmail
    |-sshd-+-4*[sshd---bash---su---sh]
    |      |-sshd---bash---su---sh---vi
    |      `-sshd---bash---pstree
    `-syslogd

Do people think that looks okay?  (apart from the few ssh's lying around)

I'm worried that this might be affecting form-email cgi scripts etc.

Anyone got any ideas?

Thanks,

Tony
