XML

<log4net>
      <appender name="ConsoleLogger" type="log4net.Appender.ConsoleAppender">
         <!-- A1 uses PatternLayout -->
         <layout type="log4net.Layout.PatternLayout">
            <conversionpattern value="%-4timestamp [%thread] %-5level %logger %ndc - %message%newline" />
         </layout>
      </appender>
 
      <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
         <file value="C:\Logs\NotificationServices\Events.log" />
         <appendtofile value="true" />
         <maximumfilesize value="5000KB" />
         <maxsizerollbackups value="2" />
         <layout type="log4net.Layout.PatternLayout">
            <conversionpattern value="%date %level %thread %logger - %message%newline" />
         </layout>
      </appender>
 
      <root>
         <level value="ALL" />
         <appender-ref ref="RollingFile" />
         <appender-ref ref="ConsoleLogger" />
      </root>
 
   </log4net>

This is my configuration file. I have been able to generate the logging perfectly
but the problem is that out of random the logging fails, FAILS IN THE SENSE THERE IS ONLY ONE LOG STATEMENT GENERATED EVERY SECOND MY SERIVE IS ACTIVE. So that is my issue.

Solution 1

Debug your code. Use unit tests to block test the log writer creation and confirm that the log writing code is valid. Without seeing your configuration for the logging that is about all I could suggest.

[Update]
You may need to revisit all the instances in your application where you attempt to write to the log. It may be that in one or more of those instances you are not providing appropriate arguments to the logger. Make sure that the values you are sending through are always initialized. You may be able to narrow down where this is occurring by stepping through your processes to find out what action from a user's perspective is causing the error. This should usually happen with the use of unit testing and such, but if that isn't available, there is no reason why you can't do it manually as well.

<log4net>

<appender name="ConsoleLogger" type="log4net.Appender.ConsoleAppender">

<layout type="log4net.Layout.PatternLayout">
<conversionpattern value="%-4timestamp [%thread] %-5level %logger %ndc - %message%newline">

<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="C:\Logs\NotificationServices\Events.log">
<appendtofile value="true">
<maximumfilesize value="5000KB">
<maxsizerollbackups value="2">

<layout type="log4net.Layout.PatternLayout">
<conversionpattern value="%date %level %thread %logger - %message%newline">

<root>
<level value="ALL">
<appender-ref ref="RollingFile">
<appender-ref ref="ConsoleLogger">

This is my config file representing logging. When I debug the code i get perfect logging but its out of random this error keeps popping up.

Nothing ever happens "at random" in software. Please review my updated answer.

Hey thanks for quick reply but I'm afraid i verified for what all u have said. The log is generated all the time Except for certain periods( that's why used the term 'random'). Is there any other basic thing I am missing.
Thanks again for such a quick reply.
