(92) Implementation-defined execution resources.
PowerAda maps all Ada tasks to the underlying POSIX threads provided by AIX. Thus limits imposed by the operating system are reflected into the execution environment. Most limits (max threads per process, max memory available to a process, etc) are configurable at the system level. The PowerAda runtime will return descriptive error messages when a limit is violated. See your system administrator if you find a limit to be too small.
