550 Hz warn-level log spam on dirauth (“[warn] Weighted bandwidth is 0.000000...”)
[warn] Weighted bandwidth is 0.000000 in node selection for rule weight as directory
very often. Today, it's been seen 19602 times.
At one point today I saw 7690 of these in 14 seconds. That's about 550 Hz.
rransom says it might be because all dirauths have bandwidth weight 0 and that bwauths sets dirauths to 0. Haven't yet checked what more it takes to end up here though.
