Hi Ron,

Thanks for your reply.
Please see the Log4net setting for my application 
<root>
                <level value="INFO"/>
                <appender-ref ref="RollingLogger" />
                <appender-ref ref="EventLogAppender" />
        </root>


<appender name="RollingLogger"
type="log4net.Appender.RollingFileAppender">
                <param name="File"
value="E:\Pages\Health\PrePricingBatch\Logs\" />
                <StaticLogFileName value="false" />
                <lockingModel
type="log4net.Appender.FileAppender+MinimalLock" />
                <appendToFile value="true" />
                <maxSizeRollBackups value="10" />
                <rollingStyle value="Date" />
                <datePattern value="yyyy\_MM\_dd\.\l\o\g" />
                <layout type="log4net.Layout.PatternLayout">
                        <conversionPattern value="%d %logger[%t]
%-5level - %m%n" />
                </layout>
</appender>

Since there are many users accessing the application and want to write
the information for each process we used the locking model
"MinimalLock".

Thanks,
Siva

> Currently we are facing some issues with the log4net configuration in our 
> project. I am looking for help on this.
> We are getting the following error in the log4net log file:
> Error: Probable I/O race condition detected while copying memory. The I/O 
> package is not thread safe by default. In multithreaded applications, a 
> stream must be accessed in a thread-safe way, such as a thread-safe wrapper 
> returned by TextReader's or TextWriter's Synchronized methods. This also 
> applies to classes like StreamWriter and StreamReader.] 
> We are using the rollinglogfileAppender with the rolling style as "Date" and 
> the locking model as "log4net.Appender.FileAppender+MinimalLock".
> When nearly 250 users in our application tries to write to the log file it is 
> coming with the above error message.
> Any help is greatly appreciated.
