500 napja megy a HUP

500 napja megy a HUPtrey@portal:~$ uptime

7:27PM up 500 days, 6:27, 1 user, load averages: 0.27, 0.21, 0.14

Sajnos ahogy nezem a NetCrafton atfordult a szamlalo. Nehany operacios rendszer eseten 497 napnal 0-ra valt a Netcraft szamlaloja
:-(

A magyarazat:

Additionally HP-UX, Linux, NetApp NetCache, Solaris and recent releases of FreeBSD cycle back to zero after 497 days, exactly as if the machine had been rebooted at that precise point. Thus it is not possible to see a HP-UX, Linux or Solaris system with an uptime measurement above 497 days.

Why do some Operating Systems never show uptimes above 497 days ?

The method that Netcraft uses to determine the uptime of a server is bounded by an upper limit of 497 days for some Operating Systems (see above). It is therefore not possible to see uptimes for these systems that go beyond this upper limit. Although we could in theory attempt to compute the true uptime for OS's with this upper limit by monitoring for restarts at the expected time, we prefer not to do this as it can be inaccurate and error prone.

Suck :-)
