> Key: LOG4NET-618
> URL: https://issues.apache.org/jira/browse/LOG4NET-618
> Project: Log4net
> Issue Type: Bug
> Components: Core
> Reporter: David Kadleček
> Assignee: Dominik Psenner
> Priority: Major

> Version: 2.10.0 (Jira says Version with id ' 2.10.0' does not exist.)
>
> In one of our production environments, the Thread which asynchronously processes log events ( Log4j2-TF-1-AsyncLogger) sometimes freezes in the native method FileOutputStream.write. The AsyncLogger is using RollingFileAppender, which is using old blocking IO access. Since we are unable to reproduce it anywhere else, we assume it's connected to this particular virtual environment setup.
>
> However, we would like to try NIO file appender. Unfortunately, I wasn't lucky to find any. Does any NIO file appender exists? Maybe unofficial? Is it planned to rewrite File appenders to use NIO approach when dealing with files?
>
> Bellow is a stacktrace of the async thread. It stays in the native method FileOutputStream.write forever but no new byte is written into the log folder.
