Troubleshooting

1. After an import, my database is not showing any results, and when manually try to run a query (from console), I get:

  $ 4s-query kosa  
  4s-client.c:306 kb=kosa waiting for lock on segment 0 on 2a01:4f8:151:33c5::2 port 6734  
  4s-client.c:306 kb=kosa waiting for lock on segment 0 on 2a01:4f8:151:33c5::2 port 6734  
  4s-client.c:306 kb=kosa waiting for lock on segment 0 on 2a01:4f8:151:33c5::2 port 6734  

Try:

• Editing file /etc/avahi/avahi-daemon.conf, and setting "use-ipv6=no"
• After that, restart 4s-backend, and 4s-httpd
• Also you can try, alternativally to drop your database, and re-import data:

  ( drop it)
  $ sudo 4s-backend-destroy kosa
  ( create new database )
  $ sudo 4s-backend-setup kosa
