Got to love the spin... "The servers are timed to shut down after 49.7 days of use in order to prevent a data overload, a union official told the LA Times." That would be 49.710269618055555555555555555556 days, or (curiously enough) 4294967295 (0xFFFFFFFF) milliseconds. Known problem with Win95 ('cept they call Win95 a "server"). -- Roy M.

I've heard some people say that there was a different problem that was causing them to need to reboot about that often, having to do with the applications rather than the core OS, but I don't know enough of the details to be sure. Either way, if they knew the system was going to crash every 49.7 days, and they had a process to have a technician reboot it every 30 days, and the technician shuts it down during quiet nighttime hours, that guarantees that the 49.7 day crash will be at a _bad_ time of day. They could at _least_ have done a workaround that tells the system to shut itself down at 2am on Day 45, after giving the operators a warning about "Hey, I need to shut myself down for an hour for maintenance some time in the next 4 days, is now a good time? Yes/No/Wait-5-min/Wait-1-hour" Disclaimer: I worked on the FAA's AAS debacle in the 80s (fortunately not on the unlucky "winning" contractor's team), and a number of my coworkers worked on VSCS projects - not sure if they won that round, or who their partners were.

How the heck do they keep a Win95 machine up for 49 days? I think 1 day is a more realistic MTBF.

If I knew somebody delivered me a mission critical system like that, I'd sue. The system required a human in the loop to periodically do action XY, or it would reliably fail? And the system before didn't? And it wasn't there as a fallback? The mind boggles. Even more interesting: how many heads have rolled due to this? -- Eugen* Leitl <a href="http://leitl.org">leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net [demime 1.01d removed an attachment of type application/pgp-signature]

None, of course. Microsoft is the new IBM. As in, "Nobody ever got fired
for buying Microsoft..."
