Strange behaviour 'DailyRollingFileAppender', two process one log4j configuration file

Hi everydoby.

I'm having a strange behaviour with a log4j configuration. I hva two different process running from two different virtual machines. Both of then read their log4j configuration from the same configuration file:

----------------------------------------------------------------------------------------------
log4j.rootCategory=DEBUG
log4j.logger.FileChecker=DEBUG,FileChecker
log4j.logger.AlertChecker=DEBUG,AlertChecker

#
# FileChecker is a DailyRollingFileAppender
#
log4j.appender.FileChecker=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FileChecker.file=./log/mylogRecibir.log
log4j.appender.FileChecker.datePattern='.'yyyy-MM-dd
log4j.appender.FileChecker.append=true
log4j.appender.FileChecker.layout=org.apache.log4j.PatternLayout
log4j.appender.FileChecker.layout.ConversionPattern=[%c] %-5p %d{ISO8601} - %m%n
#
# AlertChecker is a DailyRollingFileAppender
#
log4j.appender.AlertChecker=org.apache.log4j.DailyRollingFileAppender
log4j.appender.AlertChecker.file=./log/mylogSend.log
log4j.appender.AlertChecker.datePattern='.'yyyy-MM-dd
log4j.appender.AlertChecker.append=true
log4j.appender.AlertChecker.layout=org.apache.log4j.PatternLayout
log4j.appender.AlertChecker.layout.ConversionPattern=[%c] %-5p %d{ISO8601} - %m%n
----------------------------------------------------------------------------------------------

(in both of the process java code I do:
private static Logger logger = Logger.getLogger("AlertChecker");
.....
PropertyConfigurator.configure(IPegasoProperties.IPEGASO_PROPERTIES_FILE); //the logj4j configuration file
)

It happens that when day changes old logging files are not renamed properly; instead they are overwritten.

Also, when log files are from an older day (process are stopped); the first process I start roll the log file properly, but the second overwrite his log (don't do the roll).

I'm tested new versions and log4j and the problem is the same.

Could anybody help me?
