Speaking of uptimes - where I work, in our data center Cisco switches and load balancers for some reason always become flaky after 300+ days of uptime - weird resets, close_waits and other such things. Older Sun OS releases (8 and below) also get flaky after 200+ days uptime (we have had apps doing zero size reads on log files in a loop, processes hanging on startup etc.). Linux boxes have so many updates that they hardly cross 60+ days uptime. The only shining stars of rock solid uptime are all heavily loaded HP-UX 11i DB Server boxes - 1000+ days uptime and literally work like they were freshly booted!
