http://issues.apache.org/bugzilla/show_bug.cgi?id=42151 Summary: StackOverFlow in flush() method of LoggingOutputStream Product: Log4j Version: 1.2 Platform: Sun OS/Version: Solaris Status: NEW Severity: normal Priority: P2 Component: Appender AssignedTo: log4j-dev@logging.apache.org ReportedBy: [EMAIL PROTECTED] I am using Log4j as the logging utility for a J2EE (JDK version 1.4) application hosted on Weblogic server 8.1 sp2 running on Solaris 8. The problem (StackOverFlow) occurs in the production environment when several jobs are run in parallel. The jobs start at 3:00 am and the error occurs between 9-10:30 am every day, but it is not associated with any job in paricular. We are unable to replicate this in dev, as the dev machines cannot handle the parallel processing of so many jobs. When we run the jobs one after another, there is no error. The exact setup being used is as follows: 1) Each job is run using an instance of a class called WorkflowBo, which gains access to Log4j via its constructor in the following way: m_logger = Logger.getLogger(p_loggerName); e_logger = Logger.getLogger(p_loggerName + "_err"); 2) We are using an appender that we downloaded off the Log4j forums called ArchivedDailyRollingFileAppender, as it zips up old log files. The file is available from: http://mail-archives.apache.org/mod_mbox/logging-log4j-user/200405.mbox/% [EMAIL PROTECTED] The exact excexption that we see is pasted below.
