 ( i have seen this issue on  many sites)
 the problem is that, while saving any custom-menu,
 it gives frequently error:
 `PHP Fatal error: Out of memory (allocated xxxx) .... on `wp-
 includes/functions.php,  line 3350`
 it is `wp_list_filter` function. in the start of that function, i have
 included this script:

 echo '<pre>';print_r(debug_backtrace());
 and i have counted how many times `wp_list_filter` executes and how heavy
 data it processes on each loop.. look this file, i have included only
 first 5 "debug_backtrace: results (because after 20nd loop php crashed,
 because of out of memory):

 please help.

 i cant save menus, i cant do anything like that, it crashed with "out of
 memory". i know that i should increase memory limit, but evidently , WP
 has issue.
