“Out of memory” errors:
These errors occur when a process in your stack attempts to utilize more memory than your infrastructure has available. Often, that specific process will fail, but subsequent requests—and any processes running at the same time—will operate normally. In those circumstances, it can be difficult to identify the root cause. In some cases, however, frequent or recurring out-of-memory events could indicate that there is either an issue with the application, or a certain tier of the stack is too close-to-capacity to safely handle the activity taking place on it—for example, page requests, cron jobs, or even normal background operations. Random occurrences of this error are not uncommon and should not be a cause for concern. Repeat occurrences (more than a few times per day) can indicate that there is a problem with your application or the health of your stack. If these types of errors occur frequently on your cluster, the most common solution is an infrastructure upsize. Acquia Support may also be able to assist with diagnostics.
