I changed MaxRequestsPerChild to 500. As expected, the processes restart before they take the system down, but that's only after each process reaches about 25% RAM consumption.

Just a quick snapshot of my current 'top' output:

   PID USER NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND

  3740 www-data   0  258m 221m 4544 S    0 22.0   1:13.73 0 apache2

  8339 www-data   0 53016  35m 4960 S    0  3.5   0:06.63 0 apache2
  8387 www-data   0 52416  34m 4840 S    0  3.5   0:06.20 1 apache2

Thanks for the suggestion. This is a good work-around until the leak is fixed.
