php - Symfony clear cache and Maximum function nesting level of '100' reached -

-

this question has answer here:

hello trying run following console command 

console cache:clear --env=prod

but got following error

fatal error: maximum function nesting level of '100' reached, aborting! in vendor\symfony\symfony\src\symfony\bundle\twigbundle\loader\filesystemloader.php on line 66

executing --no-debug throw same error, when run following command

console cache:clear --env=prod --no-optional-warmers

the cache cleared , generated fine, twig templates not generated , generated on runtime when user navigate site, causing user wait longer usual.

what can cause error?, seems error when generating views, why , how fix this?, thanks

i have symfony 2.6 , php 5.5

this due xdebug.max_nesting_level php setting, defaults 100.

this directive limits recursion 100 calls may not enough rendering form in template if render whole form @ once (e.g form_widget(form)). fix can set directive higher value (either via php.ini file or via ini_set(), example in app/autoload.php) or render each form field hand using form_row.
