Ralph Goers reopened LOG4J2-625:
--------------------------------
After looking at this again this is not a duplicate of LOG4J2-542. That has to
do with deserialization on a different server where the Exception class may not
be available. I'm not sure what the cause of this is.
> Serialization error with SocketAppender and Asynch Logger
> ---------------------------------------------------------
>
> Key: LOG4J2-625
> URL: https://issues.apache.org/jira/browse/LOG4J2-625
> Project: Log4j 2
> Issue Type: Question
> Components: Appenders
> Affects Versions: 2.0-rc1
> Environment: Ubuntu 12.04, Java 7
> Reporter: Bryan Hsueh
>
> I'm testing a simple SocketAppender, which works fine until I switch to
> asynchronous loggers. Once I turn on async logging, I get:
> 2014-04-29 21:17:26,029 ERROR Serialization of LogEvent failed.

> The client just does a LogManager.getLogger().info("{}", "hello").
> The server just creates a SocketServer:

> Am I missing something? Please advise.
