nutsdb: server hang without log

[daflyinbed]

caddy 2.8.4 cache-handler v0.13.0 in global option:

    cache {
        nuts {
            configuration {
                Dir /tmp/nuts-configuration
                EntryIdxMode 1
                RWMode 0
                SegmentSize 1024
                NodeNum 42
                SyncEnable true
                StartFileLoadingMode 1
            }
        }
        storers nuts
    }

/tmp/nuts-configuration is created, but caddy response internal server error to client.

Hello @daflyinbed do you have some logs about that? Are there any error logs during startup?

[daflyinbed]

No. I will try to reproduce this problem in test environment in next few weeks. ( I've reverted back to using Varnish, so this is not my top priority task )

Same here

@long2ice same question then, do you have some logs about that? Are there any error logs during startup?
Can you give me more context?

@daflyinbed Thanks for your reply! I tried many storages which support file storage, but none of them work fine for me. For badger, it cost much memory and I didn't found any solution. For nutsdb, it will hang up after some time. This is my minimal caddy file:

{
        admin :2019
        cache {
                api {
                        souin
                        prometheus
                }
                nuts {
                        path /data/nuts
                }
                ttl 1h
        }

                        tls
                }
        }

                        route @secure_cdn {
                                proxy {
                                        proxy_protocol v2

                }
        }
}

For who have same problem, I finally use https://github.com/sillygod/cdp-cache

That's not a suitable solution because the module you are mentioning is not maintained and doesn't implement fully the RFC. By the way I'm already working on a filesystem storage with TTL based eviction but that takes time to work on that beside my daily work and other projects I'm contributing to.

Thanks! Looking forward to it. I think It is useful for many people who do not want too high performance by providing a simple filesystem storage.
