I'm still waiting for the next failure.
Meanwhile, I run this from the crontab every 5 minutes :

#!/usr/bin/perl -w
#
@A=`/usr/bin/top bcn1 ` ;
for my $a (@A)
{
  if ($a =~ /^\s*(\d+)\s+.+?\s+\d+\s+\d+\s+(\d+)M\s+(\d+)M\s.*dumper/)
  {
     if (($2>400) || ($3>400))
        {
                print "Found a memory-eating dumper process\n$a" ;
                `kill $1` ;
                sleep(10) ;
                `kill -9 $1` ;
        }
  }
}
