Summary: Effective Level of logger randomly changes
Product: Log4j
Version: 1.2
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: critical
Priority: P2
Component: Other
AssignedTo: [email protected]
ReportedBy: [email protected]
Under heavy load scenarios (20 users, 1 hit per second each), the effective
logging level will randomly change to erroneous values (Set at Info, changes to
debug or fatal, etc). This prevents some messages from printing, and others
printed when they should not be.
Code.
if (logger.isDebugEnabled()) {
System.out.println("Start");
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Logger level: " + logger.getEffectiveLevel());
System.out.println("Done");
}

System.out.println is only used in this case to ensure it is always printed so
it can debug. Normally would use log4j.debug/etc.
rootlogger and class level loggers are all set up for ERROR in this case.
