H A Ddevpts.rst25 Total count of pty pairs in all instances is limited by sysctls::
27 kernel.pty.max = 4096 - global limit
28 kernel.pty.reserve = 1024 - reserved for filesystems mounted from the initial mount namespace
29 kernel.pty.nr - current count of ptys
34 ``sysctl kernel.pty.reserve``.
36 In kernels older than 3.4 sysctl ``kernel.pty.max`` works as per-instance limit.
