      Description

      Moodle 1.8 does not install if memory limit is less than 40M in PHP 5.2.0; previous versions of PHP require less memory because the used memory calculation is wrong.

      To do:
      1/ fix installation docs
      2/ fix checked limits in installer

      This fix should prevent frequent incomplete install reports caused by running out of memory.

          Official min limit is 40M now. It may work with lower memory settings but even 40M may not be always enough. Normal Moodle pages try to increate the memory to 96M, cron and other scripts to 192M.

          Please note that code is tested mostly with the higher memory settings, not with enforced 40M limit.

          Ciao Petr
          I had the same problem you described. I had incomplete install caused by running out of memory on Moodle 2.0 and moodle didn't risw up any warning. Maybe this check should be improved!!!!
