> --------------------------------------------------------------------
>
> Key: LOG4J2-2592
> URL: https://issues.apache.org/jira/browse/LOG4J2-2592
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.11.0, 2.11.2
> Reporter: Dávid Kaya
> Assignee: Gary Gregory
> Priority: Critical
> Fix For: 2.12.0
>
>
> 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)
