Test case failing on rhel 7.6 ppc64le platform

[SantoshMagdum]

Hi All,

I had build the nginx binary on rhel 7.6 ppc64le (version 1.17.1.1rc0) from source code - https://github.com/openresty/openresty.
Please note that, I had copied and used ppc64le compiled LuaJIT code while building openresty (nginx).
Below command I used to compile the openresty -

./configure --with-cc-opt=-O2 --with-http_image_filter_module --with-http_dav_module --with-http_auth_request_module --with-poll_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_ssl_module --with-http_iconv_module --with-http_drizzle_module --with-http_postgres_module --with-http_addition_module --with-debug --add-module=/usr/openresty/openresty_test_modules/nginx-eval-module --add-module=/usr/openresty/openresty_test_modules/replace-filter-nginx-module;

And then tried to execute the test cases for 'lua-resty-dns-0.21' like below -

[root]# pwd
/usr/openresty/openresty/openresty-1.17.1.1rc0/build/lua-resty-dns-0.21
[root]# prove -r t

NOTE: The 'lua-resty-dns' version is 0.21 which was downloaded as part of openresty bundle.

I am getting below test case failures. The errors "lua udp socket read timed out" repeats for all failing test cases but I have kept below uniq errors.

Please help suggest if I need to export any specific environment/setup any additional service or should try any compiler flag/somehow increase timeout value to make these test cases pass?
