06.25 GMT Housekeeping
FYI, every morning at precisely 06:25 GMT the forums do some housekeeping and don't respond for 4 minutes or so.
Not interesting, not important. Just a nugget of a factoid Wink

RE: 06.25 GMT Housekeeping
At 22:25 Pacific Time, I try to log into the Linn Forum, and get to watch the download thingy, cycle around for 4 minutes.

At this Exact moment, I am considering brushing my teeth, contemplating interdimensional shifts, how to find new levels of sound quality, how to better shield my electronics, and minimize vibrations in my stereo system.

At that same moment, some nice gentlemen in white coats are knocking on the door.

Just a small factoid. Tongue

Timster: this is normal behavior. Every computer thatt runs 24/7 services needs to be able to do some things for itself. Linn has to find a timeslot where as less as possible people suffer from it.
I have a website which runs several things starting at 4am, but I can get away with that as the website is voor .nl customers only. I only have to do a few things that can only happen past 9am. that makes it tricky.
I once was partly responsible for a system in Amsterdam where people in Europe, the USA, Japan and Arabia would have to use. The only time that it wasn't used was saturday morning real early.

RE: 06.25 GMT Housekeeping
Thanks Tin. I realise it has to do it sometime but now we know precisely when (I wonder if NAS's do something similar?)
Anyway, now we know we can go and do something more useful instead for 4 minutes... umm.. (I'll leave that hanging...)

Paul, shouldn't you be tucked up in bed by then? I heard that in the 7 ages of man, babies and oldies share the same sleep patterns. I'm sure the nurses must wonder why your light's still on and mutter away amongst themselves about that ol' codger messin' aboot in his room (picturing grampa Simpson...).

Nah, I'd bet that you're all wrong; perhaps at 06:25 every morning, Ivor Tiefenbrun turns up for work, unplugs the server and plugs in the kettle to make his morning cup of tea? Tongue

KDS/1 (music) + ADSM (AV) -> KK/1 -> 350A + miniDSP time & phase aligned 345 rear sub
KDS Renew -> Homebrew fixed attenuator -> 2250/D -> 212 and Sizmik front sub (bedroom)
MDSI -> 104C (awaiting installation in my kitchen)
MDSI -> Shahinian Arc (installed at my mum's house)

This sounds more likely.

It doesn't matter to anyone which is why I guess they do it but there are fewer reasons today than ever as to why there would need to be a daily outage. Just a function of cash, design and planning but it is a forum not a telephony system and seems reasonable.

6:25 is a very specific time. Look in /var/log/ on one of your Linuxes and you'll see what I mean.

I just hacked into the forum server and it looks like my theory was correct; the evidence resides in line 2 of the crontab file:

Code:
forum@linn:/etc$ cat crontab

# m h dom mon dow user    command
17 *    * * *    root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *    itiefenbrun    /sbin/halt #tea time
25 6    * * *    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

I wrote -your- Linuxes. You are confusing Timster, he wakes up around 5 something each morning and it is way past his afternoon nap.

So when Ivor plays with funky new dips it's just hobnobs in his tea! Big Grin
