Executing remote commands to tbg15 with 1 ssh session, rather than 1 command 1 ssh session, helps. However, if commands are to the other 18 vpcs in class A internal ips, the ssh channels to them need to go thru the ssh channel of tbg15. This is not viable, especially true for real-time functions like dashboard (frequently executing top to all vpcs).
After a few successful executions, the ssh channels are blocked somehow. Of course, putting random delay between the executions help but is not scientific enough.
