Expensive parser function calls
There is a limit of 500 to the expensive parser function count, i.e. the number of calls of expensive parser functions, which are (as of revision 40528):
- #ifexist - used to change the behavior of a template depending on whether a particular page exists. If the limit on this counter is exceeded, additional #ifexist calls will act as though the pages they query do not exist.
- PAGESIZE Pages that exceed this limit are automatically categorized into Category:Pages with too many expensive parser function calls.
