Hi there, I would really appreciate if anyone out there could help me with this problem. Basically I am running a Java server that creates a number of threads and I have setup log4j so that each thread logs to its own file. My log4j.properties file looks like this (1 thread only): ... #-------------------------------------------- # Appender MAIN #-------------------------------------------- log4j.appender.MAIN=org.apache.log4j.RollingFileAppender log4j.appender.MAIN.layout=org.apache.log4j.PatternLayout log4j.appender.MAIN.layout.ConversionPattern=%d %-5p %c %m%n log4j.appender.MAIN.file=${TraceFile}.log log4j.appender.MAIN.ImmediateFlush=true

Hi there,
I would really appreciate if anyone out there could help me with this problem. Basically I am running a Java server that creates a number of threads and I have setup log4j so that each thread logs to its own file. My
log4j.properties
file looks like this (1 thread only):
...
#--------------------------------------------
# Appender MAIN
#--------------------------------------------
log4j.appender.MAIN=org.apache.log4j.RollingFileAppender
log4j.appender.MAIN.layout=org.apache.log4j.PatternLayout
log4j.appender.MAIN.layout.ConversionPattern=%d %-5p %c %m%n
log4j.appender.MAIN.file=${TraceFile}.log
log4j.appender.MAIN.ImmediateFlush=true
#-------------------------------------------
# Appender TO (used by thread #0)
#-------------------------------------------
log4j.appender.T0=org.apache.log4j.DailyRollingFileAppender
log4j.appender.T0.layout=org.apache.log4j.PatternLayout
log4j.appender.T0.layout.ConversionPattern=%d %-5p %c %m%n
log4j.appender.T0.file=${TraceFile}_thread_0.log
log4j.appender.T0.ImmediateFlush=true
This works perfectly but the following happens when I shut down the server (the code terminates threads first and then the server):
log4j:ERROR Failed to flush writer, java.io.InterruptedIOException

This does not happen all the time i.e. sometimes I am able to shut down the server without getting any exception at all. Any ideas? Your help would be much appreciated.
Thanks in advance,
