apache - ThinkingSphinx on production : Cannot assign requested address -

i have problem cannot fix today. happened me @ least once don't remember i've done fix it.

i'm deploying rails 4 application (with apache , passenger , using ruby 2.1) on own server using capistrano 3. cannot use thinking-sphinx because of following error :

fatal: bind() failed on my.ip.address : cannot assign requested address

this error strange because can use without error command index not rebuild.

i'm working directly on server ssh trying solve problem. have start searchdby own ? have stop apache during rebuilding ?

i don't know begin.

last word : strangest part working cannot restart it.

i've joined configuration files.

thank in advance help.

i found solution. mistake came thinking_sphinx.rbfile. needed same configuration on development.

preprod:   mysql41 : 9312   enable_star: true   min_prefix_len: 3 

finally, problem came pid file path not specified , have reconfigure sphinx rake ts:configure before rake ts:rebuild. solved deployment problem capistrano 3.

i hope else.
