> Key: LOG4NET-506
> URL: https://issues.apache.org/jira/browse/LOG4NET-506
> Project: Log4net
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 1.2.15
> Environment: Windows Server 2008 R2, Windows Server 2012 R2
> Reporter: Frédéric Delaporte
> Attachments: SiteAlone_log4net.txt, SiteWithSvc_log4net.txt

>
> We have many applications running on the same server.
> Some are windows services running under "Local system" identity, others are
> IIS hosted web sites running under "Application pool" identity.
> All do log through RollingFileAppender to D:\Logs\ to their own file log
> (filename specific to each application).
> They log through AdoNetAppender too.
> Since we have upgraded Log4Net from 1.2.13 to 1.2.15 on all services and some
> web sites, upgraded IIS web sites cease being able to log to D:\Logs\. SQL
> logs still work. Non upgraded web site are still able to log to D:\Logs\.
> Our services start before our web sites.
> Stopping all services then restarting a web site allows it to log again in
> D:\Logs\. Restarting a second web site (having a different application pool)
> while the first is still running does not allow the second one to log again
> in D:\Logs\ (Application pool identity give different identity to each pool).
> Activating log4net debug trace on a web site, and comparing failure cases to
> working cases, we get following diff:
> _failing case_
