On the Beach (Feb 04 2010)

So yeah, turns out the science database was having a migraine, not just a headache. I had to give it another swift kick last night. But after some rough seas this morning it seems to have just suddenly righted itself (at least for now). The symptoms were kind of new - Informix would be stuck at a checkpoint, while there was literally zero disk i/o on the system for upwards of an hour. Stopping/restarting Informix helped both times, but didn't seem to solve anything in the long term. What's more mysterious is the cause. We were running fine last week, even after starting Astropulse. What changed? We were quick to blame some extra Astropulse analysis queries (as they wrecked us before) but we still got the same symptoms after killing those. Was it merely the weekly post-outage recovery, which normally floods all our servers? Well, this was the first time we had an outage recovery while Astropulse was involved in a while, so maybe that's part of it. In any case, we're keeping a closer eye on the science database these days.

Just watch out for those deadlocks. Stupid question but is some lock not being updated (released) because it is sitting in a disk buffer rather than being written to disk and some other part getting caught in a race because it hasn't been updated?

Any word on what the problem today is? Hopefully downloads will work for the weekend...

There's a reason given with that message:

Message from server: Project is temporarily shut down for maintenance

It means what it says.

I'm getting the following when trying to upload completed WU's:

2/11/2010 6:12:36 AM SETI@home Temporarily failed upload of 31dc06ac.32631.2935.10.10.159_0_0: connect() failed

happening at Beta, too... Why is the upload server off-line?

Good afternoon,

"Server Status" shows upload servers in the green.

However, I am unable to upload two results at this point. (Another is close to finishing)

Can anyone advise?

Thanks
