I don't think the questioner would have asked the question if (s)he had written an obvious repetition like this (even in quite a complex situation).

This appears to be 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 https://github.com/iATSPayments/com.iatspayments.civicrm/issues/68 it go away) by removing one line of code from IATS. Now, I happen to think this line of code is not required - 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. Sending a PR to remove the line eileenmcnaughton added a commit to eileenmcnaughton/com.iatspayments.civicrm that referenced this issue Mar 10, 2015 eileenmcnaughton https://pantheon.io/docs/alternative-php-cache/ having to be recompiled each time. Pantheon provides APC by default across all plans, but https://www.drupal.org/node/838744 the size of 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 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 cannot redeclare 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, 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 cannot redeclare class 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. Troubleshooting I got a fatal error about redeclaring a class in Drupal core; what should I do? In some rare cases, there is a known issue with APC where it attempts to load a file that has already been cached. For example: Fatal error: Cannot redeclare class InsertQuery_mysql in ... on line 87 If this happens often, a workaround would be to place the following at the top of the file in question: if (!class_exists('NAMEOFCLASSBEINGREDECLARED')) { then closing the condition with the corresponding bracket at the bottom: } How do I clear the APC opcode cache? Sometimes, due to (very rare) corruption, the APC opcode cache will need to be cleared. Manual To do this manually, write a smal
