U may need to increase the kernel parameter nflocks. Whenever sendmail tries to process a mail queue it will lock that queue file using file locks . If u ran out of nflocks then the sendmail will not be able to lock the queue files . Check the current value of nflocks using 'sysdef |grep nflocks' and increase the value to a higher one.
