Sining Ma created KAFKA-848:
-------------------------------

             Summary: StackOverFlowError
                 Key: KAFKA-848
                 URL: https://issues.apache.org/jira/browse/KAFKA-848
             Project: Kafka
          Issue Type: Bug
          Components: producer 
    Affects Versions: 0.7.1
         Environment: Win7 64 bit
            Reporter: Sining Ma
            Assignee: Jun Rao



I am using kafka 0.7.1 right now.
I am using the following log4j properties file and trying to send some log 
information to kafka server.



log4j.rootLogger=INFO,file,stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] %p %t %m (%c)%n

log4j.appender.file=org.apache.log4j.RollingFileAppender
#log4j.appender.file.FileNamePattern=c:\\development\\producer-agent_%d{yyyy-MM-dd}.log
log4j.appender.file.File=${AC_DATA_HOME}\\lmservice\\tailer-aggregator.log
log4j.appender.file.MaxFileSize=100MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern= %-4r [%t] %-5p %c %x - %m%n
log4j.appender.file.layout.ConversionPattern=[%d] %p %t %m (%c)%n

log4j.appender.KAFKA=kafka.producer.KafkaLog4jAppender
log4j.appender.KAFKA.layout=org.apache.log4j.PatternLayout
log4j.appender.KAFKA.layout.ConversionPattern=[%d] %p %t %m (%c)%n
log4j.appender.KAFKA.BrokerList=0:localhost:9092
log4j.appender.KAFKA.SerializerClass=kafka.serializer.StringEncoder
log4j.appender.KAFKA.Topic=test.topic


# Turn on all our debugging info
log4j.logger.kafka=INFO, KAFKA
log4j.logger.org=INFO, KAFKA
log4j.logger.com=INFO, KAFKA

When I run the program without KafkaLog4jAppender, everything is fine. Then I add KafkaLog4jAppender.
The producer can send messages through KafkaLog4jAppender to Kafka server.
However, after the producer send messages for a while. I see StackOverflowError. It seems that the producer or something else is recursively calling some functions.
This error will come out from many threads. I only copy 3 threads call stack below.
