Subject Log file name gets duplicated
Date Thu, 27 Oct 2011 18:48:11 GMT


I've got a situation when my application creates multiple log files, e.g.:


1). Greenrain Connect 2011-10-21.log

2). Greenrain Connect 2011-10-21.log Greenrain Connect 2011-10-21.log

3). Greenrain Connect 2011-10-21.log Greenrain Connect 2011-10-21.log
Greenrain Connect 2011-10-21.log


Here come more details about our environment:


1). log4net.dll file version


2). Application config has the following log4net configuration:


    <appender name="Greenrain Connect"

      <param name="File" value="Application Log\"/>

      <param name="RollingStyle" value="Date"/>

      <param name="DatePattern" value="Greenrain Connec\t yyyy-MM-dd.lo\g"/>

      <param name="StaticLogFileName" value="false"/>

      <appendToFile value="true"/>

      <maximumFileSize value="1048576KB"/>

      <!--This property is ignored for Rolling Style Date-->

      <staticLogFileName value="false"/>

      <layout type="log4net.Layout.PatternLayout">

        <conversionPattern value="%date{yyyy-MM-dd HH:mm:ss} [%thread]
%-5level %C{1}.%M (%F:%L) - %m%n"/>





      <!--Level value would always be ALL as all appenders will inherit this
value. Root's level is the lowest level any appender will have.-->

      <level value="ALL"/>

      <appender-ref ref="Greenrain Connect"/>




3). I noticed the following scenario when log files get duplicated:


Example 1

We have exe App1.exe that uses Component1.dll. When App1.exe does not call
any function in Component1.dll, when log file name is generated correctly
(e.g. "Greenrain Connect 2011-10-21.log"). As soon as App1.exe calls
functions from Component1.dll, the log file name gets duplicated (e.g.
"Greenrain Connect 2011-10-21.log Greenrain Connect 2011-10-21.log").


Example 2

We have two applications App1.exe and App2.exe that both write logs into the
same log file. In this case we get log file with correct name (e.g.
"Greenrain Connect 2011-10-21.log") and second log file with duplicated name
(e.g. "Greenrain Connect 2011-10-21.log Greenrain Connect 2011-10-21.log").


Is there anything wrong with my config settings?


Thank you in advance for any comments.
