4239	PREG_BACKTRACK_LIMIT_ERROR encountered during WP import	ryan	ryan	"The WordPress importer uses preg_match_all to slurp items from the import file.  Large items can cause a PREG_BACKTRACK_LIMIT_ERROR.  This can be avoided by bumping pcre.backtrack_limit, but that isn't very friendly. Instead, the importer shouldn't use preg_match_all.  There are other ways of retrieving the items.
