This host should be banned. It's running AWOL and the owner seemingly has no clue.

10723 "error while computing" tasks.
509 valid tasks
13 invalid tasks

Upon further inspection, all of the valid tasks appear to be from 13th of September 2024. So essentially it's erroring out every single one of the new tasks.

Boinc host error detection isn't working. The code is supposed to only give one task every 24 hours until a task is successfully returned valid, whereupon it will issue two tasks, then double for every valid returned result. But it's broken on that host.
