--------------------------------------
Hi [~davidkaya.ysoft],
You marked this ticket with version 2.11.2 but the stack trace shows version
2.11.0.
May you please try with 2.11.2 and post that stack trace if it still occurs?
Thank you,
Gary
> StackOverflowException when server not reachable with SocketAppender

> Key: LOG4J2-2592
> URL: https://issues.apache.org/jira/browse/LOG4J2-2592
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.11.2
> Reporter: Dávid Kaya
> Priority: Critical
>
> SocketAppender crashes log4j with {{StackOverflowException}} when the server
> where the log file should be sent is not accessible. It looks like
> {{toString()}} contains recursion.
> This also happens in 2.11.2 (even though log shows 2.11.0).
> This does not happen in 2.8.2 ( {{toString()}} methods were not there in that
> version)
