MajorLinux a852f7b7bd ClamAV fleet caveat: add follow-up on the polite-CPU-on-1vCPU edge case
Same-day correction. The proposed per-droplet relaxed alert (>95%/30m)
turned out to also trip on a 1 vCPU box during low-traffic weekly scans,
because there's literally no real load for nice 19 to yield to —
clamscan opportunistically fills the vCPU and DO sees 100% utilization
regardless of `%nice` vs `%user` split. Documents the three realistic
options (accept page / switch to clamdscan / disable alert) and the
underlying limit (no DO threshold can distinguish polite from impolite
CPU when the box is fully utilized).
