Out of memory: Killed process 3890279 (php)

Out of Memory (OOM) Kill occurs in Linux systems when memory is exceeded or reaches critical levels that could otherwise force the system into a state of instability. Since virtualize systems (ours included) have fixed memory allocations, running out of memory requires you to do the following:

• Optimize your current usage of system resources
• Create a Swap file to increase available memory. Swap is a substitute for Physical Memory and will not perform as well depending on your use case, but can help provide a buffer against OOM kills.
• Upgrade to a larger plan with more memory
