Platform: AIX 6.1. SSH Tectia Server: 6.1.9
When logging in to a SSH Tectia Server, I can notice a gap of about 2 seconds after the process "ssh-user-fileio" process is launched.
Please, see the extract of the SSH Tectia Server log:
When ssh tectia server does the fork for launching the new process, it closes all inherited file descriptors. Hosts that have "unlimited" amount of file descriptors may suffer this penalty. For the session that starts the SSH Tectia Server, Tectia recommends to specify with a given number the amount of file descriptors, do not have it set as "unlimited", as it will attempt to close all of them.
