(Doc ID 2189837.1)

Last updated on JULY 11, 2017

Applies to:

Solaris x64/x86 Operating System - Version 11.3 and later
Information in this document applies to any platform.
In a system with an application that clients will connect with SSH sessions, in the peak of connections during a given week every month SSH randomly disconnects sessions from clients.

Goal

Every month, a least during a given week, there is a huge number of connection to the application in the server.  All of them through SSH.  In the peak of the activity randomly SSH disconnects users.

We need to adjust parameters in the client to keep alive the session while there no activity as user is waiting for response from the application.  The same on the server side we can adjust parameters to keep alive those connections.
