To cut a long story short: if you did not change anything with root environment settings after Tue Oct 14 09:58:41 2008 (your localtime) there is nothing wrong with this user or the operating system. I'd suggest you uninstall that ssh software completely and install from scratch.
Somewhere up in the thread you mention that that Tectia ssh software is being used because it was somewhat more secure than OpenSSH. If nobody at your datacenter can name exactly where this additional security compared to the current version of OpenSSH is you might consider using OpenSSH instead. Reason is that you will get faster and better response to questions related to a product that is widely used compared to some niche product.
