NSTRPUSH
NSTRPUSH defines the maximum number of streams modules that
are allowed to exist in any single stream at any given time on the
system.
16
Specify integer value. For more information, see Specifying Parameter Values.
This parameter defines the maximum number of streams modules that can be pushed onto any given stream. This provides some protection against run-away processes that might automatically select modules to push onto a stream, but it is not intended as a defense against malicious use of streams modules by system users.
Most systems do not require more than about three or four modules in any given stream. However, there may be some unusual cases where more modules are needed. The default value for this parameter allows as many as 16 modules in a stream, which should be sufficient for even the most demanding installations and applications.
If your system needs more than 16 modules in a stream, the need should be carefully evaluated, and the demands on other system resources such as outstanding bufcalls and other factors should also be carefully evaluated.
