unexpected EOF error in alpine-osv, debian, download-cves

This seems to be occurring when loading the nvd mirror data - may be due to the streaming changes made the other day, and may indicate that we need to improve our Cron scheduling

Start by reproducing the unexpected EOF in the alpine-osv, debian, and download-cves jobs while loading the NVD mirror data. Read the recent streaming changes and inspect the Cron scheduling for these jobs. Done means the affected jobs complete reliably without unexpected EOF errors and the underlying failure is covered by a regression test.
