I think both Dan and Zeffie have missed the original two posters' point; 
it's not that sendmail isn't starting back up, but rather that it 
appears to go down more often.

Sendmail was designed in the days when there were lots of ways to send 
mail, besides the Internet, and it still has code to support all of 
them.  It was designed when email was considered a "least-important" 
service, with supporting local users the top priority.

Because of this design, it will automatically shut itself off if the 
server load becomes too high; that is configurable through sendmail.cf, 
and should be through other configurations methods as well.

The Sun Cobalt "heartbeat" monitor will attempt to restart sendmail 
every fifteen minutes, but if server load is still high it will be 
unsuccessful, and you'll get that message.

I'm not sure why your server is experiencing higher load when you 
install blocklists.  Are you sure all the blocklists you've chosen are 
working properly and replying in a reasonable timeframe?  Have you 
tried manually testing the blocklists to see if they're putting a load 
on your server?
