Ddevpts.txt19 Total count of pty pairs in all instances is limited by sysctls:
20 kernel.pty.max = 4096 - global limit
21 kernel.pty.reserve = 1024 - reserved for filesystems mounted from the initial mount namespace
22 kernel.pty.nr - current count of ptys
25 This feature was added in kernel 3.4 together with sysctl kernel.pty.reserve.
26 In kernels older than 3.4 sysctl kernel.pty.max works as per-instance limit.
