Description
I'm using nginx on Digital Ocean with default Ubuntu distribution and nginx development ppa. I also saw the same behavior on multiple other cloud providers.
The problem is that even when serving small number of domains (~3-5), nginx gives me the [emerg] could not build the server_names_hash, you should increase server_names_hash_bucket_size: 32 error and I have to change otherwise perfect default configuration.
Can you make the size of server name hash larger by default, or, even better, calculate optimal size at runtime? Pretty annoying that the server cannot determine such things by itself.
This is probably related to #352.
Note:
See TracTickets
for help on using tickets.
The name you are trying to use is likely larger than what fits into 32 bytes - which is the optimal size as calculated by nginx according to CPU ID.
