I guess the 2 main reasons are (in no specific order):
a/ Need to move the machine (or power shortage)
b/ Need to upgrade the kernel or sysvinit.
c/ Memory leaks in the kernel/hardware drivers/sysvinit.

for reason a/ it does not depend on Linux or Debian but on the machine's
environment. For reason b/, it's clearly non-trivial to do and involves a
LOT of kernel hacking. For c/, it can be debugged.
BTW, does any1 know of an operating system which can have its kernel
upgrading 'on the fly'? (some embeded system?)

Is there a known "longest uptime record" ?
