sphinxsearch returns "failed to send client protocol version"

Question

On some of my servers, doing a sphinx php query returns that error. Searching google I can't find anything except this is part of why the error came out:

// send my version
    // this is a subtle part. we must do it before (!) reading back from searchd.
    // because otherwise under some conditions (reported on FreeBSD for instance)
    // TCP stack could throttle write-write-read pattern because of Nagle.
    if (!$this->Send($fp, pack('N', 1), 4))
    {
      fclose($fp);
      $this->error = 'failed to send client protocol version';
      return false;
    }

The close I've found is this http://www.sphinxsearch.com/forum/view.html?id=4919

But I do not know where the sphinxapi.php is (I installed using manual compile) and not sure if that's a good idea.

Anyone has any idea?

Answer 1

I just had the same issue on my server, and I realized I did not start the searchd daemon at all.

Hope this helps
