When deploying APIcast 2.11 there is this warning shown:

nginx: [warn] could not build optimal variables_hash, you should increase either variables_hash_max_size: 1024 or variables_hash_bucket_size: 64; ignoring variables_hash_bucket_size

The request is to investigate whether one of the variables should be increased.

Note: There is no unexpected behaviour as a result of this log entry and the only concern is with what is being logged and whether it shoudl be fixed.
