Expected Behavior

Error: Maximum function nesting level of '256' reached, aborting! in /var/www/html/data/BeanFactory.php on line 249

Possible Fix

Issue is here (SugarBean.php):

        if ((!$this->disable_vardefs && empty($loaded_definitions[$this->object_name]))
            || !empty($GLOBALS['reload_vardefs'])) {
            VardefManager::loadVardef($this->module_dir, $this->object_name);

Can you please indicate the exact CRM version you are using as /var/www/html/data/BeanFactory.php on line 249 does not point correctly to a function in latest that I can see.

@tsmgeek It was about 9 months ago. It was 7.10.27 version. I saw this old fix when I updated to a new version yesterday.

/data/BeanFactory.php:

Does this happen on a freshly installed system, or on the live demo?

Normally when I've seen this happening, it was caused by infinite loops in custom code. Typically, on-save logic hooks that call Save method, or something similar with workflows (or both).

@pgorod We have been using the application about three years in the production. We use a custom code. Once we saw those errors. We applied this fix and there were no those errors.
Ok, I'll try to find the old application container with those errors in the registry and check it. Thanks for the information about infinite loops in custom code. I'll try to check it again.

@pgorod You were right, the issue was in custom code. We added empty vardefs.php files for custom modules which don't use DB. It's ok now. I'll close PR. I think the issue can be closed. Thanks!
