bug or could I do something else to prevent these errors? I'm using Ubuntu 8.04 LTS with PHP 5.2.4. Edit/Update (from comments): I use the Zend Framework Autoloader and these error never occurred before I enabled APC. A few moments ago I get for example that error: Fatal error: require(): Cannot redeclare class zend_db_adapter_abstract in /paths/app/lib/Zend/Db/Select.php on line 27 apc php share|improve this question edited Jan 1 '11 at 20:30 asked Jan 1 '11 at 19:19 Poru 2,799144782 1 Read the whole error message. Do not include the said file twice. Use include_once. Or failing that, wrap all definitions in if (!class_defined("xxx")) { –mario Jan 1 '11 at 19:51 In addition to only using include_once, try and re-architect the application to make use of class autoloading, so that PHP will only include files when needed. Also stick to common-sense things, like one class per file, etc. –Rob Jan 1 '11 at 20:10 1 what do you mean by xxx? is xxx actually the class you want to load? –The Surrican Jan 1

of having to be recompiled each time. Pantheon provides APC by default across all plans, but the size of error cannot redeclare class cakephp the APC memory cache (apc.shm_size) varies depending on the service level. Frequently Asked Questions Can APC be used as a cache backend on Pantheon? Yes, APC can be used as a http://stackoverflow.com/questions/4575341/php-with-apc-fatal-errors-cannot-redeclare-class cache backend or a "key-value store"; however, this is not recommended. APC lacks the ability to span multiple server environments. Instead, Pantheon provides Redis as a caching backend, which has better performance. What happens if the APC memory cache is too small? If the size of the scripts loaded exceed the size of the APC cache, the cache will be flushed and rebuilt, https://pantheon.io/docs/alternative-php-cache/ resulting in slow execution time. Symptoms of this will include the following message in dev environments and in watchdog logs: Warning: require_once(): Unable to allocate memory for pool. In these circumstances, either increasing the SHM size by upgrading your account, or reducing the amount of scripts read by PHP by disabling unneeded modules typically resolves the issue. To learn more about how much memory your site is using, visit the site's New Relic dashboard. How can I determine what my current APC settings are? Search for shm_size in phpinfo. See Securely Working with phpinfo. Can the shm_size be configured manually? No, as this is not a runtime configuration, the shm_size cannot be changed. If a greater shm_size is needed, then the two options available are to optimize the codebase to operate within the service level, or to upgrade the site account for a larger shm_size allocation.

This appears to be error cannot something we just don't want to know about - see http://help.getpantheon.com/pantheon/topics/fatal_error_require_once_cannot_redeclare_class_insertquery_mysql One punter says that "The real solution is to remove the Call-time pass-by-reference from your code. " However, I found that I could FIX it (make it go away) by removing one line of code from IATS. Now, I happen to think this line of code is not required error cannot redeclare - it seems to have spawned itself all over the CiviCRM code-base more like a virus than enzyme. This is the dreaded line... // get merchant data from config $config = CRM_Core_Config::singleton(); Now, since we aren't using $config we know we don't need the variable. But, do we need to call CRM_Core_Config::singleton() at all? My understanding is that line IS overloaded and does instantiate 'something' @totten might know. But I'm pretty comfortable arguing the something isn't required here because a) I find other processors without it & b) you don't get to constructing a payment processor object without having core pretty heavily loaded.
