It has been running for more than 300 days now. But, when we add up (213690753 +3535601 + 69121220 + 2373602539 + 10577537 + 1026646 + 35425802) / 100 / 86400, the number of days is only 129. Looks like the values of /proc/stat are rolling over at 260 days. Is this a bug ? Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
