Hi Guys
For years I've wantted to have a machine that reports it's uptime as
being over a year. I've come close several times, but there was always
something the cause me to reboot the machine - Like a breif power cut.
However, at last I've managed it. One machine, marvin, has been running
the same kernel for 380 days - I managed it some days ago and didn't
even realise. :-)
This is not an idel system either. It is the work horse of my DMZ
handling all incomeing and outgoing emails, spam assissin, web server
and primary DNS server for my domain, etc.
So what magical things happend when you get over a hear of uptime? Well
ps lists the process start time as just a year, rather than a month and
a day:
