> -----------------------------------------------------------
>
> Key: LOG4J2-1191
> URL: https://issues.apache.org/jira/browse/LOG4J2-1191
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.4.1
> Reporter: Wolfgang Grossinger
> Priority: Major
>
> We are currently logging with Log4j2 to a file and want to replace this/add logging over Logstash via TCP/IP. When we do this (we add an according Socket appender) the logging just hangs after a while. There are 2 problems at the moment:
> 1.) The communication to Logstash is blocket - this may be because of Log4j2, because of a Java Library, because of Lostash etc. (we are still investiging about this)
> 2.) The second problem is definitely a problem with Log4j2: when this problem occurs, NOTHING is logged at all -> the whole logging just stops, no logging to a file, no logging to sysout, nothing. If the logging is not async, the whole application hangs. What we would expect is, that a failure in one appender does neither harm other appenders or at least loggers and does not kill the whole application.
