Description

nstrpty limits the number of streams-based PTYs that are allowed system-wide. When sending data to PTY devices (such as windows), a PTY device must exist for every window that is open at any given time.

nstrpty should be set to a value that is equal to or greater than the number of PTY devices on the system that will be using streams-based I/O pipes. Using a parameter value significantly larger than the number of PTYs is not recommended. nstrpty is used when creating data structures in the kernel to support those streams-based PTYs, and an excessively large value wastes kernel memory space.
