panic in Caddy plugin about souin HOT 4 CLOSED

Hi @knadh thank you for your issue. The panic comes from the singleflight package, I have to check why that happens, which "map" is concurrently accessed/written. That's a high priority bugfix.

It would be great to have a reproducible test case 🙂

I will use the stress tests to debug that then.

This is from a site that receives few a thousand requests per minute. Have been unable to pinpoint what triggers this, unfortunately. Sometimes it's a few seconds between crashes, sometimes it's half an hour. I've disabled caching altogether.

@knadh
try changing to nutsdb or redis, crash caddy should not occur. I tested under heavy load.

With this config

cache {
        nuts {
            path /tmp/nuts-path
        }
    }
