Major Issue, Trixbox not coming up anymore in IE, also issues with Firefox and module update freezes

I dont know whats happening but lately several Trixbox installations on different networks seem to have contracted some sort of bug thats going around. The symptoms are the following

1. Will not display in IE, only Firefox, the page looks like its going to load but then comes up as Page Cannot be Displayed
2. In Firefox, if you go to Extensions page, "Create New Extension" is gone also when you click on an extensions details on right hand side, the entire details does not load. there is no scroll bar to see further down so it stops around the fax email fields
3. When I try to do a Module Update it gets stuck around 4% of downloading a new framework and just freezes, during this time if I were to Ping the machine it would spike up giving me latency from 20ms, to 300ms and as high as 700ms, out of nowehere. As soon as I exit the page, latency stops

The system will continue to work so long as I dont touch anything, and the status bar shows everything in the Green in terms of performance. its literally as if the GUI has gone Nuts

Usually I would not be worried, but the same issue occurred on a completely separate box and installation.

I went ahead with a yum update and now under /maint I have 2.6.1.13 but still the issues occur

Any help would be great

Thanks
