You need to raise the respective kernel parameter. Alternatively, reduce PostgreSQL's consumption of semaphores by reducing its max_connections parameter (currently 13). > The PostgreSQL documentation contains more information about configuring your system for PostgreSQL. Apparently your kernel doesn't have enough semaphores to allow 8.1 and 8.3 to run concurrently.
