Re: log files get reset at 12:00 noon every day

[Baron Schwartz]

I had this problem as well a while ago.  Upgrading solved it.  Search 
the mail archives for my message for specifics.  Be sure you are using 
the latest versions from the log4net site, not the sourceforge site -- 
it is stale there.

Yes, datePattern specifies when it should roll over. The pattern I used specifies a daily roll 
over. The log files do roll over correctly at midnight. So at midnight last night, a new log file 
was created named WS.error.20051028.log (the "log" appends "log" to 
the filename).
But then, why does it roll over again at noon? The log file will be full of 
entries until 11:59:59, and then the next second the file is empty and starts 
to record again at 12:00:00.

Again, this works on my local machine, but on the servers Ive deployed it to it 
does the above strange behaviour.

Does anyone have any clues???

<datePattern value=".yyyyMMdd.&quot;log&quot;" />

Isn't datePattern the parameter to specify when the rollover should
occur? If it is, you have it set to daily. Not sure why it would
choose 12pm rather than 12am but I am curious what effect the
&quot;log&quot; string would have on that...

Here is the snipped from my log4net config file:

       <!-- ERROR LOG - text file that rolls on a daily basis -->
       <appender name="ErrorRollingFileAppender" type="log4net.Appen> 
der.RollingFileAppender">
               <filter type="log4net.Filter.LevelRangeFilter">
                       <levelMin value="WARN" />
                       <levelMax value="FATAL" />
               </filter>
               <rollingStyle value="Date" />
               <datePattern value=".yyyyMMdd.&quot;log&quot;" />
               <file value="D:\\myfolder\\Logging\\hidc2\\WS.error" />
               <appendToFile value="true" />
               <param name="StaticLogFileName" value="false" />
               <layout type="log4net.Layout.PatternLayout">
                       <conversionPattern value="%d %-7p %c  &quot;%m&> quot; 
%P{SessionId} %P{ProfileId} %P{XmlData} %n" />
               </layout>
       </appender>

Is anything wrong with it?

Thanks for your help,
Simon.
