I've just upgraded the OpenSSH server version on my VPS from 4.3 to 5.8. For a reason each SSH session I make takes now at least 40MB Ram (It took 3-4MB before the upgrade).
My VPS has only 64MB Ram so I really need that ram, and can't find a reason how the ram usage came up by 1000%. OpenSSH is not that RAM-intensive.
The weird thing is when I try to open a SSH-1 session, it takes only 2MB ram, which is fine. Problem is that SSH-1 is not secure enough.
How can I debug the problem, or how can I get it fixed?
I'm using Debian 4 (etch).
