It looks like an Akka issue or more accurately your question requires a
level of knowledge in Akka which I personally do not have.

Hi,
I am using Play 2.4.6 on CentOS 6 server with Java 8 for deploying
production application. I am using logback logging in 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:Couldnot 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]]]

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] <mailto:[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 causing timeout for logger? or something else?
My production box is 1 Core 4 GB with CentOS 6 and play application runs
within a docker on this box.

Suraj
