Thanks for the replies!
I just checked the modules I have and all seems good. I have a version installed now that consumes excessive CPU after 994 days of up time. These are my main cores so it is hard to take them down for upgrades so I want to make sure I get a version that is known to be good and not have issues like I am experiencing now.
What if the latest version of XOS is blank? (Edited)
One other question, I have BD 8800 G48Tc modules that are not listed on that site. I just noticed this, why wouldn't they be listed?
