 postgres[14947]: [1-1] LOG:  could not create IPv6 socket: Address family not supported by protocol
 postgres[14947]: [2-1] FATAL:  could not create semaphores: No space left on device
 postgres[14947]: [2-2] DETAIL:  Failed system call was semget(5432018, 17, 03600).
 postgres[14947]: [2-3] HINT:  This error does *not* mean that you have run out of disk space.
 postgres[14947]: [2-4] ^IIt occurs when either the system limit for the maximum number of semaphore sets (SEMMNI), or the system wide maximum number of
 postgres[14947]: [2-5]  semaphores (SEMMNS), would be exceeded.  You need to raise the respective kernel parameter.  Alternatively, reduce PostgreSQL's
 postgres[14947]: [2-6]  consumption of semaphores by reducing its max_connections parameter (currently 512).
 postgres[14947]: [2-7] ^IThe PostgreSQL documentation contains more information about configuring your system for PostgreSQL.
 postgres[14947]: [3-1] LOG:  shmctl(25755662, 0, 0) failed: Invalid argument
 postgresql:  failed

 Как с этим бороться ?

max_connections = 100 если уменьшить до 100 конектов то postgresql
стартует но вот это остается :
LOG:  could not create IPv6 socket: Address family not supported by protocol

И как всетаки решить проблему целиком ?
