Getting the attached error. We are running on a cluster with 24 nodes. Any idea what could be causing this?

Could you paste your build.sbt dependencies? do you have slf4j logger in deps?

Error is raised during ActorSystem creation it has nothing to do with scredis yet.

commented

As you saw in the other ticket I suspect it has to do with timeout during ClusterConnection. This has happened when the Redis cluster was in a bad state. Otherwise the applications starts just fine

commented

Maybe scredis doesn't connect because of timeout or maybe because of something else.

So far you only pasted an error saying you don't have logger library in your deps and that probably causes all scredis logs to be dropped and you cannot actually see what is going on.

  private def makeConnection(server: Server, systemOpt:Option[ActorSystem]): NonBlockingConnection = {
    val systemName = RedisConfigDefaults.IO.Akka.ActorSystemName
    val system = systemOpt.getOrElse(ActorSystem(UniqueNameGenerator.getUniqueName(systemName)))
// ^^ here is where exception is thrown

// other code 

// here is connection related code

scredis needs AktorSystem, you can provide one or it will be created by scredis.
Firstly you need to fix issue with logging and then we should be able to see what is actually going on.
