too many open files crash

[zipkr13]

Curious if this has been seen before?

Error: tonic::transport::Error(Transport, hyper::Error(Accept, Os { code: 24, kind: Uncategorized, message: "Too many open files" }))

seen on macOS, using cargo installed version of indradb-server using rocksdb

is this rocksdb under the hood crashing?

macos has very low open file limits by default. Either open a rocksdb datastore with a lower open file limit: https://github.com/indradb/indradb/blob/master/lib/src/rdb/datastore.rs#L448

Or increase the open file limit: https://docs.riak.com/riak/kv/latest/using/performance/open-files-limit/index.html#mac-os-x-el-capitan

Gotcha, makes sense. I was using a rocksdb datastore, but still likely seeing it locally due to the open file limit as you mentioned.

It's now running on GCE and I added a restart script, so it is fine, was just curious if indradb was intended to hard crash on such instances

It doesn’t have to hard crash, that’s contingent on how you’re doing error handling. To not crash, handle the error without relying on eg unwrap or expect.
