Probably just a script failed.
There's been no project people since Milo started his new job at the start of December, and it looks like the new people won't arrive for another few weeks.

Until then, no credits on external sites.

Luckily I spotted this and running the script manually is not really any trouble.
Although the main stats script has been running nicely, the boinc_stats script failed due to being unable to connect to the database.

Still no project programmers/trouble shooters either. :)

I think this is an issue for all stats sites, not just BOINCstats. Free-DC has the same issue.

Yes,it is for all stats sites, and is Climate specific and has persisted for nearly a week.

An update:

The current problems with this forum not being available for a few hours each day, as well as the missing credits exports, is apparently due to the daily backups. These are taking so long now, with the terabytes of stored data, that the other things, as mentioned above, as well as general access to the database, is impossible at times.

Les' point about data is a good one - CPDN now has about 70TB of stored data files, with multiple database records (file, parameters, workunit details &c.) for each of these.

It seems that the staff are willing to order another database server, which can be configured as a slave to the main BOINC database, and also to consider archiving more results. Meanwhile, I have at least got the stats dump to run, so hopefully boincstats will pick this up.

Thanks Milo for the status update. My site has already accepted the stats update so BOINCstats should catch up soon.

Milo, how much of that 70TB is active? Perhaps a large piece of the data could be handled as archived data (near storage rather than live storage), thus simplifying and shortening the backup process and perhaps improve over all performance/

That is one of several options that will be considered, once the new people arrive.
For now, backups are being made on odd numbered days, to allow the other programs a chance to run.

The problem is not really the size of data files (although that causes problems in other ways) but the number of database records referring to them. We can archive the older records, and have done so twice, but then they become inaccessible to users who want to look at past results. Neither Tolu nor I ever had any time to write code to let users examine archived data.

I used to have a database slave which could be used for backups (the hardware has since been retired) and I have suggested to the CPDN staff that they set up a new one.
