mmm,...met the same experience, dont know if same problem cause with your
case, but
hey,might as well check again the crontab, which might* have some typo error
or placed
a number that is not expected to be there, which has been executed at
specified interval
causing memory being eaten up to execute the process...
bottomline, out of memory brought about by careless keyboards :) hope not!
hth,
milver
