I just saw this blog entry that suggest using %processid. This would be ideal...
http://piers7.blogspot.com/2006/02/using-log4nets-fileappender-in-web.html
<appender name="File" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString"
value="C:\temp\MyApp_[%processid].log" />
However, on my system, using
<appender name="Loadtest.Debug"
type="log4net.Appender.RollingFileAppender, log4net, Version=1.2.9.0,
Culture=neutral, PublicKeyToken=b32731d11ce58905">
<param name="File" value=".\[%processid]LoadTest.log" />
Created a file name " [%processid]LoadTest.log", and showed same locking
contentions.
We have to use rollingfileappenders, because our customers require us to have
NO additional dependencies on databases.

Are you generating a lot of logs? Keep in mind that the RollingFileAppender is
not a database. Have you looking using something like MSDE and the
AdoNetAppender as a storage place for logs on each machine? This link shows how
to setup an alternate locking model on a FileAppender:
http://logging.apache.org/log4net/release/config-examples.html#fileappender
Opening and closing a file after each write will never be as fast as an
exclusive lock.

Subject: RollingFileAppender & concurrency
Hello,
We have a .Net v2 asp.net webservice that uses log4net. Our customers want
to run our product in a webgarden (multiple processes running on the same
machine). Each process, uses the same web.config, and thus the same
RollingFileAppender file name.
Will the service interleave the log calls to the single file correct? (a
simple test I did with a console app, running in two windows, didn’t interleave
correctly).
Is there a switch on RollingFileAppender to allow concurrency? Another
(file based) appender?
Thanks! J
