Hi,
I am using Play 2.4.6 on CentOS 6 server with Java 8 for deploying
production application. I am using Akka actors for doing my async tasks and
sending email is one the tasks.
>From last 2 days, I am getting following exception:
akka.ConfigurationException: Could not start logger due to [akka.
ConfigurationException: Logger specified in config can't be loaded
[akka.event.Logging$DefaultLogger] due to
[akka.event.Logging$LoggerInitializationException: Logger
log1-Logging$DefaultLogger did not respond with LoggerInitialized, sent
instead [TIMEOUT]]]

at akka.actor.ActorSystem.create(ActorSystem.scala)
at manager.EmailManager.sendHtmlEmail(EmailManager.java:63) at
My application.conf has below entry:
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-min = 8
}
}
}
logback.xml has following entries apart from other appender and logger
declarations:
<logger name="play" level="INFO" />
<logger name="application" level="DEBUG" />
<logger name="akka" level="INFO" />
However, I do not use akka logger reference defined above anywhere in my
code. Instead, I use default logger configuration where timeout is
happening:
Logger.debug("EmailActor - onReceive() : MultiPartEmail message to
[email protected]");
Each time timeout happens, I have to restart my play application.
Is it hardware issue which is restricting threads available for creating
new actor instances? or something else?
My production box is 1 Core 4 GB with CentOS 6 and play application runs
within a docker on this box.
Regards,
Suraj
