Hi,

I have a problem about rollover behaviour of log4j. Let me explain my problem step by step. I have an xml file which configures log4j for me. Here is the xml file
/**********************************************************************************************************/ <appender name="GatewayAppender" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="Gateway.log"/> <param name="Append" value="true"/> <param name="MaxFileSize" value="5000KB"/> <param name="MaxBackupIndex" value="10"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-4r %d [%t] %-5p %c [%x] - %m%n" /> </layout> </appender> <logger name="GatewayLogger" additivity="false"> <level value="DEBUG"/> <appender-ref ref="GatewayAppender"/> </logger> <root> <priority value="DEBUG" /> <appender-ref ref="GatewayAppender" /> </root>
/**********************************************************************************************************/

I also manually change the settings of log4j (like debug level) from the program at runtime. My program produces 100-200 logs every second. Sometimes I want to close the log file that is used at present and open a new file before the file reaches maximum file size. I have a command "reset log" which resets the log file and opens a new log file. This command executes these lines
/**********************************************************************************************************/ RollingFileAppender rfa = (RollingFileAppender)Logger.getRootLogger().getAppender("GatewayAppender"); rfa.rollOver();
/**********************************************************************************************************/

I also must mention that I use different threads for logging(15) and for commands. In my program generally I take exception (not always) when I call "reset log" command. Exception is
/**********************************************************************************************************/ log4j:ERROR Write failure. java.io.IOException: Stream closed at sun.nio.cs.StreamEncoder.ensureOpen(StreamEncoder.java:38) at sun.nio.cs.StreamEncoder.write(StreamEncoder.java:127) at sun.nio.cs.StreamEncoder.write(StreamEncoder.java:144) at java.io.OutputStreamWriter.write(OutputStreamWriter.java:204) at java.io.Writer.write(Writer.java:126) at org.apache.log4j.helpers.CountingQuietWriter.write(CountingQuietWriter.java:36) at org.apache.log4j.WriterAppender.subAppend(WriterAppender.java:292) at org.apache.log4j.RollingFileAppender.subAppend(RollingFileAppender.java:225) at org.apache.log4j.WriterAppender.append(WriterAppender.java:150) at org.apache.log4j.AppenderSkeleton.doAppend(AppenderSkeleton.java:221) at

/**********************************************************************************************************/ After this log4j continue to log but not rollover the file. But when I call again it works perfectly. I think I am doing something wrong but I cannot figure it out. Could you point out what am I doing wrong in my program. Thank you for your help. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
