I think this is a misjudgment in the critbit hasher, we're working on a fix.

In the meantime use -hclassic

Also confirmed very high cpu usage for varnish using critbit hash, as compared to classic hash, after cache is warmed with 100k plus of smallish (<100KB) objects.

  • status changed from new to closed
  • resolution set to fixed

We believe we nailed this with 2.1.3. We've seen similar reports and those were resolved with 2.1.3.

I'm closing this under the presumption that it's solved. Feel free to re-open if this persists after upgrading to 2.1.3.

After few hours testing everything looks ok.
