To differentiate from 775's thread, this is scheduler contacts.

Here's some scheduler contacts for this project just after it came back from switching servers:

So I got 8 tasks, at 9 scheduler contacts. Why? Why can't it download all 8 at the same time?
And are downloads even happening, because I never see any mention of a download. Or upload for that matter.

The getting tasks was part of what I was noting in another post. I wasn't sure if it was the client or the project.

What about in an earlier BOINC version?

No, it's the project as Rosetta throws 12 of them in my direction without fail.

22-Jul-2020 18:04:19 [Rosetta@home] [sched_op] CPU work request: 88293.25 seconds; 11.00 devices
22-Jul-2020 18:04:21 [Rosetta@home] Scheduler request completed: got 12 new tasks
22-Jul-2020 18:04:21 [Rosetta@home] [sched_op] Server version 707

Strangely enough, the config is set up to send multiple tasks to each host. I'll have to investigate this further following the server upgrade.
