By default, the size is set to 5m by Kong.

Had few questions regarding the usage of this shared memory.

  • Is there any way to manually override this size?
  • What happens if this shared memory is completely full?
  • I am observing a constant increase in allocated slabs for this shm. Is this something expected?

There is no way to override the value within kong.conf, but one could always change the value by providing a custom nginx template.
