A big message overwhelmed MailScanner

 From the fact that several different MailScanner processes all tried to 
process the same message, I would say your "Lock Type" is set wrong. 
What version of sendmail are you using and what operating system and 
distribution are you using?

If you are using Linux and sendmail 8.13.1 or greater, then you need to set
    Lock Type = posix
in your MailScanner.conf. You will then need to "service MailScanner 
restart".
