JBoss failed for stress test? Or Log4j?

[gan.gary]

I have a Vb6 client that consume JBoss/Hibernate. While doing the stress test for overnight, VB6 run completely and JBoss is still up but data processed half. And I found the log produced is with size: 4.01 GB (4,314,379,264 bytes) with this setting:

<appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender">
 <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
 <param name="File" value="${jboss.server.log.dir}/server.log"/>
 <param name="Append" value="false"/>

 <!-- Rollover at midnight each day -->
 <param name="DatePattern" value="'.'yyyy-MM-dd"/>

 <!-- Rollover at the top of each hour
 <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/>
 -->

 <layout class="org.apache.log4j.PatternLayout">
 <!-- The default pattern: Date Priority [Category] Message\n -->
 <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>

 <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n
 <param name="ConversionPattern" value="%d %-5r %-5p [%c] (%t:%x) %m%n"/>
 -->
 </layout>
 </appender>

Is it a known issue for JBoss? Do I need to turn on the file-rolling?

You are using a DailyRollingFileAppender which rolls over the file at midnight each day. It does not consider the file size for rollover. If you want it to be file size based then comment out this appender section and then uncomment the next section (which is for file size based rolling) in the jboss-log4j.xml :

<!-- A size based file rolling appender -->
 <appender name="FILE" class="org.jboss.logging.appender.RollingFileAppender">
 <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
 <param name="File" value="${jboss.server.log.dir}/server.log"/>
 <param name="Append" value="false"/>
 <param name="MaxFileSize" value="500KB"/>
 <param name="MaxBackupIndex" value="1"/>

 <layout class="org.apache.log4j.PatternLayout">
 <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
 </layout>
 </appender>

thanks for the solution. Can i confirm it's the (4 GB for files) size limit on windows for 32 bit NTFS?

Sorry, i did not understand the question. Are you asking if there is a limit of 4GB for file size on windows?

[gan.gary]

will log file cause JBoss terminate?

[jaikiran]

No. It won't.

thanks for your info. Looks like my client failed for reason.

BTW, DO you have any idea on failover cluster?

While trying to setup a new JBoss apps, I come across with failover clustering, does anyone have any advices on this, other than the link at Jboss doc: Chapter 16. Clustering http://docs.jboss.org/jbossas/jboss4guide/r4/html/cluster.chapt.html
& http://wiki.jboss.org/wiki/JBossHA ?
Any simple hello world exmple?
Or anyone know this: http://wiki.jboss.org/wiki/BasicClusterTest ?
It seems simple but nothing there.
