I am use drupal 6.

it seems like permission page can not save too many settings.

I have try to save permission setting, but it is just not saved into DB. I have found out this is due to "too many fields". (use content permission module). if i uncheck some fields, and then checking lesser fields, permission will be saved.

for example, if I am unchecking 2 check boxes, then checking one check box, permission will be saved.

does any one know which function the permission page used to insert result into db?

my php memory limit is 256M.
