The hashes have two parameters: ..._hash_bucket_size and ..._hash_max_size.
First you should increase hash_max_size. But if single entry can not fill
inside bucket, then nginx says that you should increase ..._hash_bucket_size.
In this case try 64 and 96 before 128. the single entry may not fill inside
server name bucket if you have at least one long server name (in your case
there is name more than 27 characters).
