Gary D. Gregory updated LOG4J2-3380: ------------------------------------ Affects Version/s: 2.17.1 > Log4j syslog appender misses writing the 1st event after syslog service is > restarted > ------------------------------------------------------------------------------------ > > Key: LOG4J2-3380 > URL: https://issues.apache.org/jira/browse/LOG4J2-3380 > Project: Log4j 2 > Issue Type: Bug > Components: Appenders > Affects Versions: 2.17.1 > Environment: CentOS 7.9 + RSyslog Service, Application deployed in > Tomcat and running on Java 11, Log4j2 version is 2.17.1 > Reporter: Loganathan > Priority: Major > > Hi Team, > We configured our application to push certain log messages to the local > system Syslog. We used the Syslog appender with RFC format. There is no > problem in writing the log to the Syslog file. But when the Syslog service is > restarted, the next message from the application is not written to the > Syslog. But subsequent messages are getting pushed properly. > I enabled the debug level log for Log4j but there is no trace of any > exception/errors when this first message is missed. I checked in the > threaddump but there is no Reconnector running. > One more thing, after restarting of Syslog service, when the 2nd message is > pushed the following log message is captured, > > {{2022-01-27 18:07:40,120 ajp-nio-0.0.0.0-8009-exec-3 DEBUG Reconnecting > localhost/127.0.0.1:514}} > {{2022-01-27 18:07:40,121 ajp-nio-0.0.0.0-8009-exec-3 DEBUG Creating socket > localhost/127.0.0.1:514}} > {{2022-01-27 18:07:40,122 ajp-nio-0.0.0.0-8009-exec-3 DEBUG Closing > SocketOutputStream java.net.SocketOutputStream@1a769d7}} > {{2022-01-27 18:07:40,122 ajp-nio-0.0.0.0-8009-exec-3 DEBUG Connection to > localhost:514 reestablished: > Socket[addr=localhost/127.0.0.1,port=514,localport=57852]}} > > I am not sure what files to be attached, please let me know if any additional > details or files are required. > Thanks, Loganathan T -- This message was sent by Atlassian Jira (v8.20.1#820001)
