Re: [akka-user] LoggerInitializationException - Akka logger timing out in Play application

[Suraj Mundada]

I looked at 
https://www.playframework.com/documentation/2.4.x/JavaAkka#Configuration 

It talks about only 2 parameters 

akka.actor.default-dispatcher.fork-join-executor.pool-size-max = 64
akka.actor.debug.receive = on


I looked up these parameters on 
http://doc.akka.io/docs/akka/snapshot/general/configuration.html but could 
not find the parameters.

My current config is 

akka {
loggers = ["akka.event.slf4j.Slf4jLogger"]
loglevel = "DEBUG"
logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
event-handlers = ["akka.event.slf4j.Slf4jEventHandler"]
default-dispatcher {
fork-join-executor {
parallelism-factor = 1.0
parallelism-max = 24
task-peeking-mode = LIFO
}
}
}

I have only one processor in my server. So, I guess parallelism-factor = 
1.0 is blocking creation of enough threads for actors. I will try 
parallelism-factor 
= 3.0 and watch it for some time if that helps.

Please let me know if I should try something else.

Regards,
Suraj

Re: [akka-user] LoggerInitializationException - Akka logger timing out in Play application

[Akka Team]

The reference.conf contains default configuration for Akka, it is nothing
you need to add or change, it is shipped together with the classes in the
akka-actor artifact. Your IDE should let you look at the contents of
dependencies, it will be in the root directory of the akka-actor jar-file.

Re: [akka-user] LoggerInitializationException - Akka logger timing out in Play application

[Suraj Mundada]

I am using Akka in Play 2.4.6 application and could not find reference.conf 
in my play application.

Also, there is no reference available in Play or Akka docs how I can add it 
in Play application.

Can you please share this info? 

Thanks,
Suraj

[Viktor Klang]

You didn't change the timeout value.

[Patrik Nordwall]

You can try to increase the timeout. You find the property in
reference.conf of akka-actor.
