Weekend Depression (May 11 2009)

Over the weekend we hit a bit of a traffic "depression" - in other words we were sending out far less work than we should and so our outgoing bandwidth dropped. Why? Well, due to a single garbled astropulse file the astropulse assimilator was bailing, and so the queue was growing, and so workunits were staying on disk longer, and so we ran out of workunit storage, and so the splitters revved down. Eric kicked the assimilator in question yesterday, and we caught up more or less.

This morning I found bruno (the upload/BOINC general admin server) was having similar mounting problems that thumper was having the end of last week - it was hanging on a mount to anakin (the scheduling server) of all things. This didn't affect anything major, but the server status page was stuck since yesterday. Anyway this time I cut to the chase and reboot the system, which helped, but the drive arrays are configured in such a way that requires human intervention on boot to get fully working again. No big deal, but some result uploads were failing for a minute or two there.

Jeff and I practiced the first rev of our anniversary talk this morning. We need to trim it down by 15 minutes. I guess there's a lot to talk about (nothing regular readers of these threads don't already know).

Thanks for the update on what was going on over the weekend.

Are the "validate error"s reported in NC-forum related to that failed result uploads ?
