Starting proxy...Failed. Starting nginx...nginx: [emerg] could not build the server_names_hash

Posted on March 7, 2016

i have installed zimbra Multi server and i have migrated a large number of domains and accounts to my mailboxes.

When i restarted zimbra mailbox, the zimbra web mail become inaccessible so i tried to restart the proxy server and then i’m blocked on this error :

Starting nginx...nginx: [emerg] could not build the server_names_hash, you should increase either server_names_hash_max_size: 512 or server_names_hash_bucket_size: 64
failed.

so i changed /opt/zimbra/nginx/conf/nginx.conf

server_names_hash_max_size 512;
server_names_hash_bucket_size 64;

no way. any suggest !! thanks.

Try changing the server_names_hash_bucket_size to 256, worked for me.

after changing : Starting proxy…Failed. Starting nginx…nginx: [emerg] could not build the server_names_hash, you should increase either server_names_hash_max_size: 512 or server_names_hash_bucket_size: 64 failed.

i tried that in multiple of 2. i have a question : should i set server_names_hash_max_size 512; or server_names_hash_bucket_size 256; or server_names_hash_max_size 512; server_names_hash_bucket_size 256; ??
