Thanks for the reply gary i appreciate it. I did state that i am not running ntp, i was in the past but figured it was causing issues, so it has not been used for quite some time. Also, i am not currently running a tickless kernel, but i have experienced this issue on tickless and "ticked" kernels. I just dont understand why a system reboot seems to resolve the issue for a day or two, considering there is nothing substantial running on the machine outside of ssh, screen and game servers.
