The ICM require two memory pipes (MPI) for each HTTP connection.
The MPI configuration in the ICM is limited by parameter
mpi/max_pipes. The default value for this paramter is 4000.
If you has 4000 for that parameter the operation system should provide 8000 operating system semaphores because eatch MPI require two semaphores.
To increase the parameter mpi/max_pipes you should take care the operation system configuration also. Follow the note 715400 to set the operation system as you need.
715400 Max. number of memory pipes (MPI) restricted to 4,000

means that no more semaphores can be created because the ICM reach the
Operation System limits.
