Temporarily disable softlimit to determine whether it's a memory limit
problem or a qmail-scanner problem. Change:

 #QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl" export QMAILQUEUE
 exec /usr/local/bin/softlimit -m 64000000 \
      /usr/local/bin/tcpserver -v -R -l 0 -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
 -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd 2>&1

To:

 QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl" export QMAILQUEUE
 #exec /usr/local/bin/softlimit -m 64000000 \
 exec  /usr/local/bin/tcpserver -v -R -l 0 -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
 -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd 2>&1

Then "svc -t /service/qmail-smtpd". If that fixes the problem, then
something like upgrading glibc or perl has dramatically altered
qmail-scanner's memory requirements, and you just need to raise
softlimit until it works.

If that doesn't fix it, you might want to check with the qmail-scanner
list.

Could be just a normal spam flood. Check your logs.
