java.lang.IllegalArgumentException from log4j

My client is facing a problem and he has sent me log file.
Log file contain few crashes as written below.

log4j:WARN Failed to set property [maxFileSize] to value "10MB". 
java.lang.IllegalArgumentException: object is not an instance of declaring class
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...

log4j:WARN Failed to set property [file] to value "../logging/serviceContainer2100.log". 
java.lang.IllegalArgumentException: object is not an instance of declaring class
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...

log4j:WARN Failed to set property [maxBackupIndex] to value "10 ". 
java.lang.IllegalArgumentException: object is not an instance of declaring class
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...

Enclosed is log4J configuration file:

# Set root logger level and appenders.
log4j.rootLogger=info, A1, R

# Appender A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# Layout for A1
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n

# Appender R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=log/DependencyAnalyzer.log
log4j.appender.R.MaxFileSize=1000KB
log4j.appender.R.MaxBackupIndex=10

# Layout for R
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n

I tried googling about this but couldn't get any satisfactory response.
Can anyone suggest where to look to dig more in to this problem or what could be possible reason?

Seems there is a wrong value of file attribute ../logging/serviceContainer2100.log comparing the value that is in your configuration file, Please would you try this log4j.properties configuration file , thant may give you some help , I just made some changes on the path of file and some appenders for test but it worked for me , waiting your feedback

# Root logger option
log4j.rootLogger=DEBUG,A1 , A,  R


 # Appender A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# Layout for A1
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n


# Redirect log messages to console
log4j.appender.A=org.apache.log4j.ConsoleAppender
log4j.appender.A.Target=System.out
log4j.appender.A.layout=org.apache.log4j.EnhancedPatternLayout
log4j.appender.A.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n


# Redirect log messages to a log file, support file rolling.
#log4j.appender.file=org.apache.log4j.RollingFileAppender
#log4j.appender.file.File=file.log
#log4j.appender.file.MaxFileSize=5MB
#log4j.appender.file.MaxBackupIndex=10
#log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n


# Appender R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=trace.log
log4j.appender.R.MaxFileSize=1000KB
log4j.appender.R.MaxBackupIndex=10

# Layout for R
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
