Wolfgang Grossinger created LOG4J2-1191:
-------------------------------------------
Summary: Log4j completely hangs in TcpSocketManager after a
while...
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: Blocker
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.
